[PATCH 32/40] stm32mp: do not add lmb memory before relocation

[Sughosh Ganu]

The LMB memory map is now being handled through data structures which
need heap memory to be operational. Moreover, the LMB memory map is
initialised as part of the board boot after relocation as part of
platform agnostic code. Remove addition of LMB memory before
relocation for the stm32mp platforms.
