cover ARM: keystone2: Build images by default

Currently we need to build each image(u-boot.uart, u-boot-nand.gph, u-boot-spi.gph) separately for all keystone2 platforms.

This series does the following:
- Move SP to end of u-boot section so that u-boot.bin can be used as build target for uart boot.
- Renames u-boot-nand.gph to MLO so that the same image can be used for NAND and SD boots.
- Includes these images in config.mk so that these images are built automatically upon calling make.

Now the updated build targets are as below:
Uart: u-boot.bin
SPI: u-boot-spi.gph
NAND: MLO
SD: MLO

Testing:

PATCH 1/5 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.

PATCH 2/5 ARM: keystone2: move the custom build rules out to keystone specific makefile

In reply to Lokesh Vutla

From: Nishanth Menon <[email protected]>

Keystone has build rules introduced by commit ef509b9063fb7 ("k2hk: add support for k2hk SOC and EVM") and commit 0e7f2dbac6ead ("keystone: add support for NAND gpheader image").

These are not reused by other platforms for the build, hence there is no clear benefit is maintaining them in the generic makefile as a build target. move these to the keystone specific make option

PATCH 3/5 ARM: keystone2: Rename u-boot-nand.gph to MLO

In reply to Lokesh Vutla

NAND boot mode, ROM expects an image with a gp header in the beginning and an 8bytes filled with zeros at the end. The same is true for SD boot on K2G platforms but the file name should be MLO.

Renaming u-boot-nand.gph to MLO, so that same image can be used for NAND and SD boots. And also not including all the u-boot only images under CONFIG_SPL_BUILD.
