net: airoha: Move airoha_qdma pointer in airoha_gdm_dev struct
Move airoha_qdma pointer from airoha_gdm_port struct to airoha_gdm_dev
one since the QDMA block used depends on the particular net_device
WAN/LAN configuration and in the current codebase net_device pointer is
associated to airoha_gdm_dev struct.
This is a preliminary patch to support multiple net_devices connected
to the same GDM{3,4} port via an external hw arbiter.
