From: Tom Stellard <thomas.stell...@amd.com>
v2: in define RADEON_INFO_MAX_SCLK use 0x1a instead of 0x19 (upstream changes)
Signed-off-by: Igor Gnatenko <i.gnatenko.br...@gmail.com>
r600: Correct the case MAX_CLOCK_FREQUENCY in get_compute_param
v3: Convert the frequency to MHz from kHz after getting it in
'do_winsys_init'
