soc/intel/pantherlake: Fix ACPI GPIO number

When using SOC_INTEL_COMMON_BLOCK_GPIO_MULTI_ACPI_DEVICES, ACPI GPIO
number is the number from its community.

In Panther Lake, each GPIO community is an individual pincntrl device.
When GPIO number is provided, the offset from its community should be
used rather than the number from the first GPIO pad.

For instance, using vGPIO_3_11 ( i.e. GPP_VGPIO3_THC1) in community 3:

from GPIO community3, INTC10BC:02/pins:
  ...
pin 82 (vGPIO_3_11) 82:INTC10BC:02 GPIO 0x40100102 0x0000003f 0x00000000 [ACPI]

-> 82 is the value the pin number/offset

GPP_VGPI3_THC1 in the SSDT:

Name (_CRS, ResourceTemplate ()  // _CRS: Current Resource Settings
    {
        GpioInt (Level, ActiveLow, ExclusiveAndWake, PullDefault, 0x0000,
            "\_SB.PCI0.GPI3", 0x00, ResourceConsumer, ,
            )
            {   // Pin list
                0x0052
            }
    }

Where "\_SB.PCI0.GPI3 is GPIO community 3.
Where 0x0052 is 82 (decimal), the offset used as ACPI GPIO number.

BUG=none
TEST=Check the number from _CRS GpinInt and GpIo objects from the SSDT
and the GPIO number used should match with the community offset.
