gpu: host1x: 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, remove a useless bitmap_zero() call. The bitmap is already zero'ed when allocated. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Thierry Reding <treding@nvidia.com>
