soc/intel/pantherlake: Enable multiple ACPI devices for GPIO

In the Panther Lake architecture, each GPIO community functions as a
separate pin control entity. Therefore, when specifying a GPIO
identifier, one should use the community-specific offset, not the number
from the first pad within the GPIO series. This is achieved by selecting
the Kconfig option SOC_INTEL_COMMON_BLOCK_GPIO_MULTI_ACPI_DEVICES within
the Panther Lake SOC Kconfig file.

The numbers within the _CRS GpioInt and GpIo objects in the SSDT should
be offsets within the community. The GPIO identifier employed should
correspond to the offset from the respective community.

Let's take an example. In the fatcat board overridetree.cb,
ACPI_GPIO_OUTPUT_ACTIVE_HIGH(GPP_E19) points to GPIO Group E. The pad
starts at 74. It is inside community 1, which starts at 48. The correct
GPIO reference is (19 + 74) - 48 = 45, or 0x002D in hexadecimal.

Here are two notable changes in the fatcat board SSDT introduced by this
commit.

- ACPI_GPIO_OUTPUT_ACTIVE_HIGH(GPP_E19)

                       "\\_SB.PCI0.GPI1", 0x00, ResourceConsumer, ,
                       )
                       {   // Pin list
  -                        0x0033
  +                        0x002D
                       }
               })
               Name (_DSD, Package (0x02)  // _DSD: Device-Specific Data

- ACPI_GPIO_OUTPUT_ACTIVE_LOW(GPP_A16)

                   "\\_SB.PCI0.GPI3", 0x00, ResourceConsumer, ,
                   )
                   {   // Pin list
  -                    0x0050
  +                    0x003B
                   }
           })
           Name (_DSD, Package (0x02)  // _DSD: Device-Specific Data

This change is verified via S0ix in Google Fatcat board with
touchscreen/touchpad attached as the wake source.

BUG=none
TEST=Check the number from CRS GpinInt and GpIo objects in the SSDT, and
     ensure that the GPIO number used matches the community offset.
     Configure touchscreen/touchpad in THC-i2c mode on factcat board and
	 enter S0ix and check that it can be waked by touchscreen/touchpad.
