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.

The error handling is off by one.  We should not free the first
"tables[i].bo" without decrementing "i" because that might result in a
double free.  The second problem is that when an error occurs, then the
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.

Changes to function "smu_suspend" in amdgpu_smu.c is a workaround.

We should get real information about if baco is enabled or not, while we
always consider APU SMU feature as enabled in current code.

I know APU do not support baco mode for GPU reset, so I use
"adev->flags" to skip function "smu_feature_is_enabled".

----
"This patch introduces new smu table type, it's to handle the
 different smu table
 defines for each asic with the same smu ip."

before:
use smu->table_count to represent the actual table count in smc firmware
use actual table count to check smu function parameter about smu table
after:
use logic table count "SMU_TABLE_COUNT" to check function parameter
because table id already mapped in smu driver,
and smu function will use logic table id not actual table id to check func parameter.
