plat-vexpress: clean memory configuration

* Cleans the memory configuration for plat-vexpress to make it easier
  to add fake and real SRAM.
* Uses common functions to check if a buffer intersects or is inside
  a memory area
* Increases number of cores from 4 to 8 for FVP flavor to support Base
  model better.

arm32: move call to teecore_init_ta_ram()

Moves call to teecore_init_ta_ram() from init_teecore() to be called
directly from platform initialization routines.  It's needed later when
the pager allocates secure DDR to store that backing pages. We don't want
to call init_teecore() until the pager is fully initialized because
init_teecore() pulls in many dependencies.

arm32: assembly routines in separate sections

Moves some assembly routines into separate sections. This helps the garbage
collecting with the linker when separating what's must be unpaged from the
rest of the code. The garbage collector in the linker works on dependencies
between sections.
