[U-Boot] [PATCH 2/2] ARM: omap3: evm: Fix distro bootcmd UBIFS and MMC support

The omap3_evm board does not boot when commit:
a47ca2cf67 ("ARM: omap3: evm: Add kernel image loading from UBIFS and EXT4")
is applied after commit:
3dde8f2037 ("Merge git://git.denx.de/u-boot-mmc")
This commit reduces the CONFIG_EXTRA_ENV_SETTINGS size and better
leverages the existing distro bootcmd infrastructure.
- Use updated UBIFS support from config_distro_bootcmd.h
- Use LEGACY_MMC naming found in am335x_evm.h and ti_omap4_common.h
- Remove extra environment content that is no longer needed
