Fabio Estevam 290e7cfdbf mx6ull: Handle the CONFIG_MX6ULL cases correctly 
Since commit 051ba9e082 ("Kconfig: mx6ull: Deselect MX6UL from
CONFIG_MX6ULL") CONFIG_MX6ULL does not select CONFIG_MX6UL anymore, so
take this into consideration in all the checks for CONFIG_MX6UL.

This fixes a boot regression.
