ACPI: AC: Quirk GK45 to skip reading _PSR

ACPI: AC: Quirk GK45 to skip reading _PSR

Let GK45 not go into BIOS for determining the AC power state.

The BIOS wrongly returns 0, so hardcode the power state to 1.

The mini PC GK45 by Besstar Tech Lld. (aka Kodlix) just runs
off AC. It does not include any batteries. Nevertheless BIOS
reports AC off:

root@kodlix:/usr/src/linux# cat /sys/class/power_supply/ADP1/online
0

root@kodlix:/usr/src/linux# modprobe acpi_dbg
root@kodlix:/usr/src/linux# tools/power/acpi/acpidbg

- find _PSR
   \_SB.PCI0.SBRG.H_EC.ADP1._PSR Method       000000009283cee8 001 Args 0 Len 001C Aml 00000000f54e5f67

- execute \_SB.PCI0.SBRG.H_EC.ADP1._PSR
Evaluating \_SB.PCI0.SBRG.H_EC.ADP1._PSR
Evaluation of \_SB.PCI0.SBRG.H_EC.ADP1._PSR returned object 00000000dc08c187, external buffer length 18
 [Integer] = 0000000000000000

that should be

 [Integer] = 0000000000000001
