mediatek mt7622: fix 300mhz typo in dts

The lowest frequency should be 300MHz, since that is the label
assigned to the OPP in the mt7622.dtsi device tree, while there is one
missing zero in the actual value.

To be clear, the lowest frequency should be 300MHz instead of 30MHz.

As mentioned @dangowrt on the OpenWrt forum there is no benefit in
leaving 30MHz as the lowest frequency.
