[PATCH] omap: tidspbridge: fix build failure on MEMBLOCK_REAL_LIMIT

[Anand Gadiyar]

MEMBLOCK_REAL_LIMIT symbol was removed by the commit e63075a3c937
(memblock: Introduce default allocation limit and use it to replace
explicit ones). This breaks build as below when CONFIG_TIDSPBRIDGE
is selected. Fix this.

Based on another similar patch [1] for vram.c. I've scrubbed the rest
of the tree for MEMBLOCK_REAL_LIMIT. Only other occurrence is in
a comment in arch/powerpc/kernel/setup_32.c [2]. Not sure what this
should be changed to.
