PS3, Line 367: pmc_clear_std_gpe_status
I would have implemented this logic in a more abstract way (w/ an assumption that we have either one Kconfig that tells me if GPE1 exists or use a macro as per https://review.coreboot.org/c/coreboot/+/84103/comment/39abef01_50206d52/

```
static void pmc_clear_std_gpe_status(void)
{
    print_std_gpe0_sts(reset_std_gpe0_status());
    if (GPE1_STS(0))
        print_std_gpe1_sts(reset_std_gpe1_status());
    
}
```

or

```
static void pmc_clear_std_gpe_status(void)
{
    print_std_gpe0_sts(reset_std_gpe0_status());
    if (SOC_INTEL_COMMON_BLOCK_ACPI_HAVE_GPE1)
        print_std_gpe1_sts(reset_std_gpe1_status());
    
}
```

why you don't need to clean GPE1 status?
