Add power profiling mode dynamic switch based on the workloads.
Currently, support Cumpute, VR, Video, 3D,power saving with Cumpute
have highest prority, power saving have lowest prority.
in manual dpm mode, driver will stop auto switch, just save the client's
requests. user can set power profiling mode through sysfs.
when exit manual dpm mode, driver will response the client's requests.
switch based on the client's prority.

when smu failed, print out the error info immediately
for debug. smum_send_msg_to_smu always return true,
so no need to check return value.

Since 12 of the 16 bytes are not initialized with anything let's ensure they're
sensibly zeroed out otherwise debugfs callers will read back garbage
(because they assume debugfs wrote sensible data back...)

Function vega10_apply_state_adjust_rules() only initializes
stable_pstate_sclk_dpm_percentage when
data->registry_data.stable_pstate_sclk_dpm_percentage is not between 1
and 100. The variable is then used to compute stable_pstate_sclk, which
therefore uses an uninitialized value.
Fix this by initializing stable_pstate_sclk_dpm_percentage to
data->registry_data.stable_pstate_sclk_dpm_percentage.
This issue has been found while building the kernel with clang. The
compiler reported a -Wsometimes-uninitialized warning.

The fan control mode can either be FDO_PWM_MODE_STATIC or FDO_PWM_MODE_STATIC_RPM.
Setting it as AMD_FAN_CTRL_AUTO will cause the fan spin faster wrongly.
This can be reproduced by:
'# cat /sys/class/hwmon/hwmon0/pwm1
38
'# cat /sys/class/hwmon/hwmon0/pwm1_enable
2
'# echo "2" > /sys/class/hwmon/hwmon0/pwm1_enable
'# cat /sys/class/hwmon/hwmon0/pwm1
122
The fan speed get faster wrongly even with its original mode echo back.

There is no reason that this gets passed back into the function
from outside the file, just reference the table directly.
