Introduce include/environment/ti/mmc.h that

for various TI boards that support MMC/SD.

This allows reuse of same environment variables

example.

While at it, move DFU-related environment variable
includes to only non-SPL builds for AM335x and
AM437x since they are not really used for SPL

Up till this commit passing NULL as input parameter was allowed, but not
handled properly.

When one passed NULL to one of this function parameters, the code was
executed causing data abort.

However, what is more interesting, the abort was not caught because of code
execution in HYP mode with masked CPSR A bit ("Imprecise Data Abort mask bit).
The TI's AM57xx SoC switch to HYP mode with A bit masked in lowlevel_init.S
due to SMC call. Such operation (by default) is performed in SoC ROM code.

The problem would pop up when one:
- Switch back to SVC mode after disabling LPAE support
- Somebody enables A bit (by executing cpsie a asm instruction)

and then the previously described exception would be caught.

The env command 'args_fit' does not define a root path, this forces us to
embed the rootfs into the FIT image. FIT images do not need to contain a
rootfs, when they do not the kernel will fall-back to the kernel argument
'root', if this is not defined the kernel will not boot. It is safe to
add this as when we do have the rootfs in FIT this argument is ignored.
As 'loadfit' is only called from the MMC boot path, use 'args_mmc' to
correctly populate 'bootargs'.

As per the latest pinmux data available for AM572x EVM,
rev A3, input should be enabled on MMC clock lines for
MMC2/2/3 for stable operation.

Further, AM572x TRM, SPRUHZ6, Revised June 2016, in
section 18.4.6.1.1 "Pad Configuration Registers" states
that input should be enabled for MMC 2/3/4 clock lines.

Enable input on MMC1 and MMC3 clock to match the latest
pinmux data. Input is already enabled on MMC2 clock for
BeagleBoard x15. Further, input is already enabled on all
MMCx clocks for other AM57xx boards (AM572x and AM571x
IDK).

Recent Linux distributions (e.g. Debian 9) include cross-compilers for
AArch64, but only for the aarch64-linux-gnu triplet only. It can thus
be expected that users will attempt to use the system cross-compiler
(instead of an aarch64-elf variant) to compile U-Boot for their ARMv8
target systems.

One key differences between an aarch64-linux-gnu and an aarch64-elf
compiler are the default settings regarding position-independent: with
the aarch64-linux-gnu compiler, the default will create and use the
global offset table.

This change-set adjusts the list of sections copied on ARMv8 to include
the GOT sections. With this added, the list matches the previous setup
for AArch32 closely.

Note that this is not an 'academic' issue, but was in fact encountered
by our QA during testing of the RK3399-Q7 BSP and resulted in an
early failure of the SPL stage during FDT setup.

SPL has been restricted to use only dev 0 based on the assumption that only
one MMC device is registered. This is not always the case and many
platforms now register several devices as expected by the spl mmc boot code
For those platform SPL_ENV_SUPPORT is broken if dev is forced to 0.

A word of warning: this commit may break SPL_ENV_SUPPORT on platforms that
do not register the same MMC controllers in SPL and in u-boot (mostly iMX6
based platforms). Fortunately none of those activate SPL_ENV_SUPPORT in
