soc: xilinx: zynqmp: Add TCG variant detection for ZU3TCG
The XCZU3TCG device shares IDCODE 0x04718093 with XCZU3TEG but has
the GPU disable eFuse bit set (Consumer Grade, no GPU). Previously,
the TEG detection branch appended "teg" unconditionally, causing
U-Boot to report the device as zu3teg and failing bitstream ID
checks for xczu3tcg bitstreams.
Check EFUSE_GPU_DIS_MASK in the TEG branch to distinguish the two
sub-variants, mirroring the existing EG/CG detection logic:
- GPU disabled -> TCG family -> "zu3tcg"
- GPU enabled -> TEG family -> "zu3teg"
Fixes: fa2f0c97af96 ("soc: zynqmp: Add the IDcode for TEG variant")
