table(a83f82e). VF cannot dump table info any more because
SMU_MSG_SetDriverDramAddrHigh/Low were deleted in the
function of smu_update_table.
Therefore, VF also needs to set driver_table address

Before, initialization of smu ip block would be skipped
for sriov ASICs. But if there's only one VF being used,
guest driver should be able to dump some HW info such as
clks, temperature,etc.
To solve this, now after onevf mode is enabled, host
driver will notify guest. If it's onevf mode, guest will
do smu hw_init and skip some steps in normal smu hw_init
flow because host driver has already done it for smu.
With this fix, guest app can talk with smu and dump hw
information from smu.
v2: refine the logic for pm_enabled.Skip hw_init by not
changing pm_enabled.

For boards greater than ARCTURUS, and under sriov platform,
swSMU is not supported because smu ip block is commented at

Generally for sriov, initialization of smu is moved to host driver.
Thus, smu sw_init and hw_init will not be executed at guest driver.

[Why]
On Navi10, and presumably arcterus, updating pp_table via sysfs would
not re-scale the maximum possible power limit one can set. On navi10,
the SMU code ignored the power percentage overdrive setting entirely,
and would not allow you to exceed the default power limit at all.
[How]
Adding a function to the SMU interface to get the pptable version of the
default power limit allows ASIC-specific code to provide the correct
maximum-settable power limit for the current pptable.

Bug fix for pcie paramerers override on swsmu.
Below is a scenario to have this problem.
pptable definition on pcie dpm:
0 -> pcie gen speed:1, pcie lanes: *16
1 -> pcie gen speed:4, pcie lanes: *16
Then if we have a system only have the capbility:
pcie gen speed: 3, pcie lanes: *8,
we will override dpm 1 to pcie gen speed 3, pcie lanes *8.
But the code skips the dpm 0 configuration.
So the real pcie dpm parameters are:
0 -> pcie gen speed:1, pcie lanes: *16
1 -> pcie gen speed:3, pcie lanes: *8
Then the wrong pcie lanes will be toggled.

zeroth element "tables[0].bo" isn't freed.
I had make "i" signed int for the error handling to work, so I just
updated "ret" as well as a clean up.
