Use the pp_od_clk_voltage sysfs file to configure the min and max value
of gfx clock frequency or to restore the default values.
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
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: 600Mhz
OD_RANGE:
SCLK: 200MHz 600MHz
2) use "s" -- set command to configure the min or max sclk frequency
$ echo "s 0 300" > pp_od_clk_voltage
$ echo "s 1 500" > pp_od_clk_voltage
$ echo "c" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 300Mhz
1: 500Mhz
OD_RANGE:
SCLK: 200MHz 600MHz
3) use "r" -- reset command to restore the min and max sclk frequency
$ echo "r" > pp_od_clk_voltage
$ echo "c" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 200Mhz
1: 600Mhz
OD_RANGE:
SCLK: 200MHz 600MHz
v2: modify the description of reset command usage - need to do "commit"
after set the restore command

v1: Use the current and custom pstate frequencies to track the current and
user-set min/max values in manual and determinism mode. Previously, only
actual_* value was used to track the currrent and user requested value.
The value will get reassigned whenever user requests a new value with
pp_od_clk_voltage node. Hence it will show incorrect values when user
requests an invalid value or tries a partial request without committing
the values. Separating out to custom and current variable fixes such
issues.

Remove redundant ras->supported, as this value
is also stored in adev->ras_features.
Use adev->ras_features, as that supercedes "ras",
since the latter is its member.
The dependency goes like this:
ras <== adev->ras_features <== hw_supported,
and is read as "ras depends on ras_features, which
depends on hw_supported." The arrows show the flow
of information, i.e. the dependency update.
"hw_supported" should also live in "adev".
