[U-Boot] [PATCH] sdhc_boot: Make mmc_get_env_addr dependant on CONFIG_FSL_ESDHC

[Fabio Estevam]

Since commit 97039ab98 (env_mmc: Allow board code to override the environment address)
mmc_get_env_addr is a weak-aliased function in common/env_mmc.c

board/freescale/common/sdhc_boot.c also defines mmc_get_env_addr, but this should be
dependant on CONFIG_FSL_ESDHC.

Add this protection in the mmc_get_env_addr definition in sdhc_boot.c.

This fixes the retrieval of CONFIG_ENV_OFFSET on i.MX28.
