[ARM] 4544/1: arm: fix section mismatch in pxa fb

Fix following section mismatch warning:
WARNING: drivers/built-in.o(.text+0x73d0): Section mismatch: reference to .init.data: (between 'pxafb_setup' and 'pxafb_init')

The warning are caused by __devinit pxafb_setup() that refers to a
variable marked __initdata.  In a hotplug scenario we would have a
reference to the freed .init.data section.  Fix this by declaring
g_options __devinitdata.
