mediatek: fix broken PCIe caused by update to 6.6.30
The patch "710-pci-pcie-mediatek-add-support-for-coherent-DMA.patch"
makes use of "syscon_regmap_lookup_by_phandle" which requires that
"syscon" be in the compatible list.
Without this patch, PCIe probe will fail with the following error:
[ 1.287467] mtk-pcie 1a143000.pcie: host bridge /pcie@1a143000 ranges:
[ 1.294019] mtk-pcie 1a143000.pcie: Parsing ranges property...
[ 1.299901] mtk-pcie 1a143000.pcie: MEM 0x0020000000..0x0027ffffff -> 0x0020000000
[ 1.307954] mtk-pcie 1a143000.pcie: missing hifsys node
[ 1.313185] mtk-pcie: probe of 1a143000.pcie failed with error -22
Fixes: 4c6e9a9943 ("kernel: bump 6.6 to 6.6.30")
