Fixes gcc '-Wunused-but-set-variable' warning:
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c: In function smu7_check_mc_firmware:
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c:4215:11: warning: variable vbios_version set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c: In function smu7_get_performance_level:
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c:5054:21: warning: variable data set but not used [-Wunused-but-set-variable]
'vbios_version' is introduced by commit 599a7e9fe1b6 ("drm/amd/powerplay:
implement smu7 hwmgr to manager asics with smu ip version 7."),
but never used, so remove it.
'data' is introduced by commit f688b614b643 ("drm/amd/pp:
Implement get_performance_level for legacy dgpu"), but never used,
so remove it.
