[U-Boot] [RFC PATCH 3/3] ARM: omap3: evm: Sync with omap3_beagle configuration

[Derald D. Woods <woods.technical@gmail.com>]

This commit does the following for OMAP3 EVM:

- Track omap3_beagle changes where possible
- Remove CONFIG_SYS_MPUCLK and CONFIG_MTD which are not needed for the
  default board configuration to work.
- Remove CONFIG_SPL_SYS_MALLOC_SIMPLE and CONFIG_SYS_MALLOC_F_LEN from
  default config. CONFIG_SYS_MALLOC_F_LEN=0x400 is set by configuration
  automatically. [allows board to boot with SERIAL_SEARCH_ALL=y]
- Use CONFIG_ENV_IS_IN_FAT because of development flexibility
- Use updated NAND layout:

	device nand0 <omap2-nand.0>, # parts = 6

	#: name		size			offset
	-------------------------------------------------
	0: spl		0x00080000(512k)	0x00000000
	1: u-boot	0x001e0000(1920k)	0x00080000
	2: u-boot-env	0x00020000(128k)	0x00260000
	3: dtb		0x00020000(128k)	0x00280000
	4: kernel	0x00600000(6m)		0x002a0000
	5: rootfs	0x0f760000(-)		0x008a0000
	-------------------------------------------------
