[PATCH v1 3/5] gpio: xilinx: Switch to use new bitmap_scatter() helper

[Andy Shevchenko]

bitmaps_scatter() produces a sparse bitmap based on the dense one
and a given mask. In this driver the given mask is hw_map, while
sw_map is of sequential bits. We may use the bitmap_scatter() helper
instead of bitmap_remap(), because it's optimized for our case.
