net: bcmasp: clean up some legacy logic

Removed wol_irq check. This was needed for brcm,asp-v2.0, which was
removed in previous commits.

Removed bcmasp_intf_ops. These function pointers were added to make
it easier to implement pseudo channels. These channels were removed
in newer versions of the hardware and were never implemented.
