[PATCH 2/5] drm/i915/bios: Round PCI ROM VBT allocation to multiple of 4

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The SPI code rounds the VBT allocation to a multiple of four bytes
(presumably because it reads the VBT 4 bytes at a time). Do the
same for the PCI ROM side to eliminate pointless differences between
the two codepaths. This will make no functional difference.
