[PATCH] pxafb: fix regression from d2a34c13e7ccec5d06eafd60e6f80ea531b34668

[Martin Jansa <martin.jansa@gmail.com>]

fbi->dev->platform_data is void * and gcc does not allow to access
!fbi->dev->platform_data->smart_update without cast platform_data to
(struct pxafb_mach_info) or assignment as used in this patch.
