ARM: spitz: fix GPIO assignment for backlight
[ Upstream commit 78ab3d352f2982bf3f7e506bfbaba7afee1ed8a9 ]
GPIOs controlling backlight on Spitz and Akita are coming from GPIO
expanders, not the pxa27xx-gpio block, correct it.
Additionally GPIO lookup tables operate with pin numbers rather than
legacy GPIO numbers, fix that as well. Use raw numbers instead of legacy
GPIO names to avoid confusion.
