P2P mode support

[C0rn3j]

I am currently running on 5.13.13 against the current latest commit.

Following Arch Wiki's Miracast page this is the output of iw [phy|dev].

Notably support for P2P is missing - on 21H1 build of W10 I can at least attempt to connect to the TV (which fails for whatever reason), but on Linux tools like GNOME Network Displays straight out refuse to work since they don't see a device with P2P support:

Supported interface modes:
         * managed
         * monitor

Is the support missing from whatever sources Realtek is providing or does the chip just plain out does not support P2P mode?

EDIT: Switched to Intel AX200 due to this issue and another high ping issue and Miracast now works fine.
