[U-Boot] [PATCH v2 3/3] ARM: omap3: evm: Sync with omap3_beagle configuration

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
