fix-pcf50633-migrate-gta02-peripherals-out.patch

pcf50633.c shouldn't know GTAxx at all.  Move to using a
platform callback to allow definition of platform devices
with pcf50633 as parent device (good for enforcing suspend /
resume ordering).  Remove all code references to GTAxx from
the sources (one string left for compatability).
