soc/intel: Select GMA v2 for ADL, MTL, TGL to reflect port/pipe defs
Intel GFX IP TRANS_DDI_FUNC_CTL register bit definitions have changed
since Tiger Lake.
This register is used to map ports and pipes to display controllers,
so reflecting the correct status is important for detecting physical
display end point devices.
This patch ensures that ADL, MTL, and TGL SoCs choose GMA version 2 to
properly reflect the updated port and pipe register definitions.
BUG=b:299137940
TEST=Build and boot google/rex successfully.
