On chips that support it, you can specificy 0 and 0xffff for
min and max and the PMFW will use that to determine the optimal
min and max. This enables optimal performance when the
user manually switches between performance levels using sysfs.
Previously we'd set soft min/max which could limit performance.

Why:
If the reg mmMP1_SMN_C2PMSG_90 is being written to during amdgpu driver
load or driver unload, subsequent amdgpu driver load will fail at
smu_hw_init. The default of mmMP1_SMN_C2PMSG_90 register at a clean
environment is 0x1 and if value differs from expected, amdgpu driver
load will fail.
How to fix:
Ignore the initial value in smu response register before the first smu
message is sent,if smc in SMU_FW_INIT state, just proceed further to
send the message. If register holds an unexpected value after smu message
was sent set, smc_state to SMU_FW_HANG state and no further smu messages
will be sent.
v2:
Set SMU_FW_INIT state at the start of smu hw_init/resume.
Check smc_fw_state before sending smu message if in hang state skip
sending message.
Set SMU_FW_HANG only in case unexpected value is detected

Add support to set/get information about different DPM policies. The
support is only available on SOCs which use swsmu architecture.
A DPM policy type may be defined with different levels. For example, a
policy may be defined to select Pstate preference and then later a
pstate preference may be chosen.
