Subject: gpu: host1x: Use the bitmap API to allocate bitmaps
Git-commit: 2e1bfb314c99de2f7b9c8280408316ad2f316de9
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
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.
