It may be necessary for some devices to specify reserved gpios in the
device-specific DTS, in addition to the reserved gpios common to all
devices with a given SoC. Remove this bitmap_fill() call so that the
settings applied to the gpio valid mask by DTS are not overridden by
the driver's reserved gpios.
