drivers/intel/gma: Increase vbt_data size

With TGL FSP v3373 onwards vbt binary size changed from
8KiB to 9KiB. Due to which cbfsf_decompression_info check
failed when trying to load vbt binary from cbfs because
vbt decompressed_size was greater than vbt_data size. This
caused Graphics Init and fw creen issues. Increase the
vbt_data to 9KiB to accommodate new vbt binary.

BUG=b:170656067
BRANCH=none
TEST=build and boot delbin and verify fw screen is loaded
