drm/amd/pm: call smu_cmn_get_smc_version in is_mode1_reset_supported.

is_mode1_reset_supported may be called before smu init, when smu_context
is unitialized in driver load/unload test. Call smu_cmn_get_smc_version
explicitly in is_mode1_reset_supported.

v2: apply to aldebaran in case is_mode1_reset_supported will be
uncommented (Candice Li)
