soc/qualcomm/ipq40xx: Return NULL for cbmem_top if DRAM is not initialized
DRAM initialization on gale requires ipq blobs to be
loaded from cbfs. vboot_locator first checks cbmem_find to see if cbmem is
initialized and contains selected region info, else it falls back to
vboot work buffer.
Since cbmem_find calls into cbmem_top to identify the location of
cbmem area, board/chipset is expected to return NULL until the backing
store is ready, which in this case until DRAM is initialized in
romstage, return NULL for cbmem_top.
BUG=chrome-os-partner:49249
TEST=Able to compile and boot to depthcharge. Doesn't crash in
imd_handle_init_partial_recovery
BRANCH=none
