401f2d91ac ARM: keystone2: configs: Move SP to end of u-boot section
Currently u-boot stack is defined at the beginning of MSMC RAM.
This is a problem for uart boot mode as ROM downloads directly to
starting of MSMC RAM.
Fixing it by moving stack to the end of u-boot section and shifting
SYS_TEXT_BASE to the start of MSMC RAM.
Updated division of MSMC RAM is shown below:
	-----------------------------------------
	|		|	|		|
	| U-Boot text	|U-Boot	| SPL text	|
	| download	| Stack	| Download +	|
	|		|	| SPL_BSS +	|
	|		|	| SPL_STACK	|
	-----------------------------------------
	[1]		[2]	[3]		[4]

[1] SYS_TEXT_BASE (Start of MSMC RAM)
[2] SPL_TEXT_BASE - GBL_DATA_SIZE
[3] SPL_TEXT_BASE
[4] END of SPL

[1] + [2] is at least 1M on all platforms, so no chance of overlap.

f06b454b1c configs: ti_armv7_keystone2: increase size reserved for initrd
9MB reserved for initrd is not enough for default ramfs used for keystone
devices, which is ~33MB. This patch increases the size up to 80MB.

e07cff1158 configs: ti_armv7_keystone2: start using armv7_common
Try to maintain as much commonality by conditionally including stuff
in armv7_common as necessary and removing the common defines from
keystone2 header.

Note: as part of this change, all keystone2 platforms will now start
using the generic u-boot prompt instead of the custom prompt.
