[PATCH] lmb: Fix LMB_MEMORY_REGIONS flag usage

[Patrice Chotard]

This patch is fixing a broken boot observed on stm32mp157c-dk2 board.

IS_ENABLED macro should be used to check if a compilation flag is set
to "y" or "m".
LMB_MEMORY_REGIONS is set to a numerical value, IS_ENABLED macro is not
suitable in this case.
