Writing to dcefclk causes the gpu to become unresponsive, and requires a reboot.
Patch ignores a .force_clk_levels(SMU_DCEFCLK) call and issues an
info message.

Writing to dcefclk causes the gpu to become unresponsive, and requires a reboot.
Patch prevents user from successfully writing to file pp_dpm_dcefclk on smu_vv11
parts and gives better user feedback that this operation is not allowed.

Hi Darren,
It would be better if the condition is " asic_type >=CHIP_NAVI10".
We assume that from navi10, this restriction is on all.
With this change, the patch is Reviewed-by: Kenneth Feng <kenneth.feng@amd.com>
Thanks.
