arm64: dts: mt7622: specify the number of DMA requests

Browse Source 
The MT7622 device tree never bothered to specify the number of virtual DMA
channels for the HSDMA controller, always falling back to the default value of
3. Make this value explicit, in order to avoid the following dmesg notification:
