csky: Use the bitmap API to allocate bitmaps
Use bitmap_zalloc()/bitmap_free() instead of hand-writing them. It is less verbose and it improves the semantic. While at it, turn a bitmap_clear() into an equivalent bitmap_zero(). It is also less verbose. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Guo Ren <guoren@kernel.org>
