Repeat enable dpm under pass-through because there is no actually
hardware-fini and real power-off when guest vm shutdown or reboot.
Otherwise, under pass-through it will be failed to populate populate
and upload SCLK MCLK DPM levels due to zero of pcie_speed_table.count.

It can avoid pr_fmt redefine warnning from linux/xxx.h like below:

Returning -EINVAL from a bool-returning function
phm_check_smc_update_required_for_display_configuration has an unexpected
effect of returning true, which is probably not what was intended.
Replace -EINVAL by false.
The only place this function is called from is
psm_adjust_power_state_dynamic in
drivers/gpu/drm/amd/powerplay/eventmgr/psm.c:106:
if (!equal || phm_check_smc_update_required_for_display_configuration(hwmgr)) {
phm_apply_state_adjust_rules(hwmgr, requested, pcurrent);
phm_set_power_state(hwmgr, &pcurrent->hardware, &requested->hardware);
hwmgr->current_ps = requested;
}
It seems to expect a boolean value here.
This issue has been found using the following Coccinelle semantic patch
written by Peter Senna Tschudin:
