On startup, the BeagleBone family of boards can occationally halt at
the U-Boot prompt.  Due to U-Boot receiving random data on the usart.

Migrate BeagleBone based boards to use CONFIG_AUTOBOOT_KEYED, user
will now have to enter the <SPACE> key to get to U-Boot prompt

For historical reason, CONFIG_SYS_TEXT_BASE has been specified
in various ways:

[1] by board/${VENDOR}/${BOARD}/config.mk

[2] by CONFIG_SYS_EXTRA_OPTIONS
    (This was "options" field of boards.cfg before Kconfig conversion)

[3] by include/configs/${BOARD}.h

[4] by configs/${BOARD}_defconfig

Most of M68K boards use either [1] or [2], both of which we want to
deprecate.  Switch them into [4], which is the newest way (Kconfig).

We still allow [3] too, because it is still used by many boards and
we expect much time for conversion.

On bootup the emmc's hw partition is always set to 0 and the partition
table is read from it. When switching to another hw partition the
partition table's id is not updated but instead the old one from
hw partition 0 is used. If there is no partition table on hw partition 0
then the code will terminate and return error even if the desired hw
partition contains a perfectly fine partition table. This fix updates
the partition table struct to correspond to the specified hw partition
before testing if the partition table is valid or not.
