drivers/fsp1_1/raminit: fix use of mrc_hob
Commit 509f469 [drivers/fsp1_1/raminit.c: Always check FSP HOBs]
inadvertently made use of the mrc_hob conditional on
CONFIG_DISPLAY_HOBS, when there is no relation between the two,
leading to MRC cache data being corrupted. On some devices this
caused RAM training to be redone, on others it resulted in a
bricked device.
Fix this by removing the condition on CONFIG_DISPLAY_HOBS.
Test: boot google/{cyan,edgar}, observe third boot and onward do not
brick device, properly use mrc_hob via cbmem console and timestamps.
