mb/google/brya/acpi: Remove erroneous _PR0/_PR3
The Linux kernel runtime D3 framework expects a PCIe device to have a
power resource in order to be properly power-manageable. The _PR0/_PR3
values were pointing at the PEG0 Device, which is not a PowerResource,
so this must have confused the RTD3 framework and RTD3 was not
functional. Removing the _PR0/_PR3 fixes the problem.
BUG=b:243888246
TEST=echo auto > /sys/bus/pci/devices/0000:01:00.0/power/control;
sleep 10;
echo on > /sys/bus/pci/devices/0000:01:00.0/power/control
After this there are no longer errors seen in dmesg about failing
to place the device into D0.
