[ARM] pxa: corgibl_limit_intensity build errors
If CONFIG_BACKLIGHT_CORGI is not selected, then corgibl_limit_intensity()
is not present. However, both corgi_pm.c and sharp_pm.c reference this
symbol, resulting in a link error.
Wrap the references with the relevant ifdefs, and avoid the resulting
NULL pointer dereference by making the code in sharpsl_pm.c also
conditional on the config symbol.
