[ARM] pxa: corgibl_limit_intensity build errors

Browse Source 
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.
