radeon/compute: Implement PIPE_COMPUTE_CAP_MAX_CLOCK_FREQUENCY
Igor Gnatenko: v2: in define RADEON_INFO_MAX_SCLK use 0x1a instead of 0x19 (upstream changes) Bruno JimĂ©nez: v3: Convert the frequency to MHz from kHz after getting it in 'do_winsys_init' Signed-off-by: Igor Gnatenko <[email protected]> Reviewed-by: Tom Stellard <[email protected]>
