mb/google/fatcat: Add ISH support with FW_CONFIG toggle
This patch adds support for the Integrated Sensor Hub (ISH) on the Fatcat mainboard. ISH can be enabled or disabled via FW_CONFIG bit 24. This allows for flexible configuration depending on the system requirements. The GPIO configuration for ISH is also updated based on CBI settings, ensuring correct initialization and communication. Verified that the device tree correctly probes ISH based on the FW_CONFIG setting: * FW_CONFIG with bit 24 set: ISH is probed successfully. * FW_CONFIG with bit 24 cleared: ISH is not probed. BUG=b:370984186 TEST=Verified ISH probing behavior with different FW_CONFIG settings using CBI.
