wifi: rtw89: pci: enable 36-bit DMA on spacemit K3

Browse source

The Spacemit K3 Pico ITX Board has a RTL8852BE pcie card behind a PCIe
root port, but the SoC doesn't have any 32 bit DMA addreseses which the
rtw89 seems to use by default. Enable 36 bit DMA ability that the driver
has when this particular root port is detected so that the driver can
probe on this SoC.
