radeon: Use request_firmware()
Loosely based on a patch by
Jaswinder Singh Rajput <jaswinderlinux@gmail.com>.
KMS support by Dave Airlie <airlied@redhat.com>.
For Radeon 100- to 500-series, firmware blobs look like:
struct {
__be32 datah;
__be32 datal;
} cp_ucode[256];
For Radeon 600-series, there are two separate firmware blobs:
__be32 me_ucode[PM4_UCODE_SIZE * 3];
__be32 pfp_ucode[PFP_UCODE_SIZE];
For Radeon 700-series, likewise:
__be32 me_ucode[R700_PM4_UCODE_SIZE];
__be32 pfp_ucode[R700_PFP_UCODE_SIZE];
