[PATCH] sparc32 vga support

sparc32 lacks vga.h, so lots of fbdev drivers won't compile.  There are no
sparc32 systems with PCI slots, so it's a bit moot.

The patch gives sparc32 a copy of the sparc64 vga.h.  It fixes sparc32
allmodconfig without mucking up fbdev Kconfig and gives us wider compile
coverage.
