drm/i915: Extend pcode mailbox interface In sandybridge_pcode_read and sandybridge_pcode_write, extend the mbox parameter from u8 to u32. On Haswell and Sandybridge, bits 7:0 encode the mailbox command and bits 28:8 are used for address control for specific commands. Based on suggestion from Ville Syrjälä.
