mb/google/fatcat/var/fatcat: Enable iGPU display using FW_CONFIG
This change enables the integrated GPU (iGPU) display on the Fatcat
board based on the FW_CONFIG setting (specifically the DISPLAY bit).
By conditionally probing the display based on FW_CONFIG, the iGPU
is dynamically enabled or disabled according to the SKU configuration.
TEST=Verified display functionality on Fatcat with the iGPU:
> cbi set 6 0x58A814 4 (DISPLAY_ABSENT):
- lspci does not list the iGPU.
- No display output, but the device boots to the OS (verified via
console).
> cbi set 6 0x5CA814 4 (DISPLAY_PRESENT):
- lspci lists the iGPU.
- Display output is functional, showing firmware and OS UI.
