The warm-reset of rk3188 socs keeps the remap setting as it was, so if
it was enabled, the cpu would start from address 0x0 of the sram instead
of address 0x0 of the bootrom, thus making the reset hang.

Therefore make sure the remap is disabled before attempting a warm reset.

Cold reset is not affected by this at all.

Most Rockchip socs have the ability to either map the bootrom or a sram
area to the starting address of the cpu by flipping a bit in the GRF.

Newer socs leave this untouched and mapped to the bootrom but the legacy
loaders on rk3188 and before enabled the remap functionality and the
current smp implementation in the Linux kernel also requires it to be
enabled, to bring up secondary cpus.

So to keep smp working in the kernel, mimic the behaviour of the legacy
bootloaders and enable the remap functionality.

The RK3399 hangs during DMA of the Designware MMC controller, when
performing DMA-based transactions in SPL due to the DDR security settings
left behind by the BootROM (i.e. accesses to the first MB of DRAM are
restricted... however, the DMA is likely to target this first MB, as it
transfers from/to the stack).

System security is not affected, as the final security configuration is
performed by the ATF, which is executed after the SPL stage.

With this fix in place, we can now drop 'fifo-mode' in the DTS for the
RK3399-Q7 (Puma).

We should invalidate the dcache before starting the DMA. In case there are
any dirty lines from the DMA buffer in the cache, subsequent cache-line
replacements may corrupt the buffer in memory while the DMA is still going on.
Cache-line replacement can happen if the CPU tries to bring some other memory
locations into the cache while the DMA is going on.

Merely using dma_alloc_coherent does not ensure that there is no stale
data left in the caches for the allocated DMA buffer (i.e. that the
affected cacheline may still be dirty).

The original code was doing the following (on AArch64, which
translates a 'flush' into a 'clean + invalidate'):
  # during initialisation:
      1. allocate buffers via memalign
      	 => buffers may still be modified (cached, dirty)
  # during interrupt processing
      2. clean + invalidate buffers
      	 => may commit stale data from a modified cacheline
      3. read from buffers

This could lead to garbage info being written to buffers before
reading them during even-processing.

To make the event processing more robust, we use the following sequence
for the cache-maintenance:
  # during initialisation:
      1. allocate buffers via memalign
      2. clean + invalidate buffers
      	 (we only need the 'invalidate' part, but dwc3_flush_cache()
	  always performs a 'clean + invalidate')
  # during interrupt processing
      3. read the buffers
      	 (we know these lines are not cached, due to the previous
	  invalidation and no other code touching them in-between)
      4. clean + invalidate buffers
      	 => writes back any modification we may have made during event
	    processing and ensures that the lines are not in the cache
	    the next time we enter interrupt processing

Note that with the original sequence, we observe reproducible
(depending on the cache state: i.e. running dhcp/usb start before will
upset caches to get us around this) issues in the event processing (a
fatal synchronous abort in dwc3_gadget_uboot_handle_interrupt on the
first time interrupt handling is invoked) when running USB mass
storage emulation on our RK3399-Q7 with data-caches on.

The dwc3_flush_cache() call was declared and used inconsistently:
 * The declaration assumed 'int' for addresses (a potential issue
   when running in a LP64 memory model).
 * The invocation cast the address to 'long'.

This change ensures that both the declaration and usage of this
function consistently uses 'uintptr_t' for correct behaviour even
when the allocated buffers (to be flushed) reside outside of the
lower 32bits of memory.

sdhci_transfer_data() function transfers the blocks passed up to the
number of blocks defined in mmc_data, but returns immediately once all
the blocks are transferred, even if the loop exit condition is not met
(bit SDHCI_INT_DATA_END set in the STATUS word).

When doing multiple writes to mmc, returning right after the last block
is transferred can cause the write to fail when sending the
MMC_CMD_STOP_TRANSMISSION command right after the
MMC_CMD_WRITE_MULTIPLE_BLOCK command, leaving the mmc driver in an
unconsistent state until reboot. This error was observed in the rpi3
