PS2:
> Tim, Subrata; can you check if this actually fixes something so we can get the commit message right.

With this patch series, on my TGL device:
```
localhost ~ # cbmem -1 | egrep -i 'pm1|gpe'
pm1_sts: 8100 pm1_en: 0100 pm1_cnt: 00001400
gpe0_sts[0]: 00209000 gpe0_en[0]: 00000000
gpe0_sts[1]: 0000000e gpe0_en[1]: 00000000
gpe0_sts[2]: 00000804 gpe0_en[2]: 00008000
gpe0_sts[3]: 00000040 gpe0_en[3]: 00012200
SMI_STS: PM1 
PM1_STS: WAK PWRBTN 
GPE0 STD STS: TCO_SCI 
ACPI _SWS is PM1 Index 8 GPE Index -1

```
They actually both look correct here.
