qca-ssdk: fix compiling for ipq60xx

Trying to compile for ipq60xx will fail with:
ERROR: modpost: "qca808x_phy_reset" [build_dir/target-aarch64_cortex-a53_musl/linux-qualcommax_ipq60xx/qca-ssdk-2024.06.13~c451136b/qca-ssdk.ko] undefined!

So, lets fix this by disabling Manhattan switch and PHY support as this is
the new 2.5G quad port switch that is not present on ipq60xx boards.
