bitmap: add bitmap_copy_le()
bitmap_copy_le() copies a bitmap, putting the bits into little-endian order (i.e., each unsigned long word in the bitmap is put into little-endian order). The UWB stack used bitmaps to manage Medium Access Slot availability, and these bitmaps need to be written to the hardware in LE order. Signed-off-by: David Vrabel <david.vrabel@csr.com>
