This patch is to add support to umd P-state function for vangogh.
It enables the "set" function of 3 sysfs nodes: pp_dpm_mclk,
pp_dpm_fclk, pp_dpm_socclk, the functions is used to set the DPM
frequency level of memclk/fclk/socclk.
Due to only after enabling the "power_dpm_force_performance_level"
sysfs node, it is allowed to set these three nodes,
so this patch also enables the "powe_dpm_force_performance_level"
sysfs node, which is used to change power profile.

This patch is to enable the "fetch" function of pp_dpm_vclk and
pp_dpm_dclk.
It allows to fetch the current frequency of vcn and dcn and their
DPM levels for vangogh.

This patch is to add new feature map macros to resolve duplicate name.
Vangogh uses one different format to name some feature bits of swSMU, it
causes some duplicate name in the existing feature map list.

When user specifies a reduced WGP(CU) config via disalbe_cu module
parameter, this does not disable the clocks which uses additional
power. This interface send active WGP number to SMU and SMU will
cooperate with RLC to power off relative WGPs.
v2: Add request active WGPs in Vangogh smu post init.

RLC is halted when system suspend/shutdown. However, due to DPM enabled, PMFW is
unaware of RLC being halted and will continue sending messages, which would
eventually cause an ACPI hang. Use the system_feature_control interface to
notify SMU the status of RLC (Normal/OFF) thus enable/disable DPM feature.

This patch is to remove one unsupported smu function, this function
will set the smu feature mask to disable all smu features in exception.
Because vangogh doesn't support to set the smu feature mask
by driver software, so this function is invalid for vangogh.

This patch is to add the fine grain tuning function for vangogh.
This function uses the pp_od_clk_voltage sysfs file to configure the min
and max value of gfx clock frequency or restore the default value.
Command guide:
echo "s level value" > pp_od_clk_voltage
"s" - set the sclk frequency
"level" - 0 or 1, "0" represents the min value, "1" represents
the max value
"value" - the target value of sclk frequency, it should be
limited in the safe range
echo "r" > pp_od_clk_voltage
"r" - reset the sclk frequency, restore the default value
instantly
echo "c" > pp_od_clk_voltage
"c" - commit the min and max value of sclk frequency to the system
only after the commit command, the setting target values by "s" command
will take effect.
Example:
1)check the default sclk frequency
$ cat pp_od_clk_voltage
OD_SCLK:
0: 200Mhz
1: 1400Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz
2)use "s" -- set command to configure the min or max sclk frequency
$ echo "s 0 600" > pp_od_clk_voltage
$ echo "s 1 1000" > pp_od_clk_voltage
$ echo "c" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 600Mhz
1: 1000Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz
3)use "r" -- reset command to restore the min and max sclk frequency
$ echo "r" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 200Mhz
1: 1400Mhz
OD_RANGE:
SCLK: 200MHz 1400MHz
