drm/i915: Rename block_size()/block_offset()

Give block_size()/block_offset() a "raw_" prefix since they
both operate on the "raw" (as in not duplicated) BDB block
contents.

What actually spurred this was a conflict between intel_bios.c
block_size() vs. block_size() from blkdev.h. That only
happened to me on a custom tree where we somehow manage to
include blkdev.h into intel_bios.c. But I think the rename
makes sense anyway to clarify the purpose of these functions.
