To support concurrency, we implement beacon filter, CQM and
ieee80211::remain_on_channel ops. Since our firmware doesn't support to TX
null packet while doing remain-on-channel, driver does this instead. To
ensure null packet send out before switching channel, patch 2/5 adds a
waiting mechanism.

The patches 4/5 and 5/5 refine things we found during developing.

v5:
  - patch 2/5
    - use owner with spin_lock to replace original third work to make
      code simpler.
  - others
    - no change

v4:
  - patch 1/5
    - define h2c/c2h struct to set/get skb->data,
      for example

      * h2c = (__le32 *)skb->data; -->
        h2c = (struct rtw89_h2c_bcnfltr *)skb->data;

      * #define H2C_CFG_BCN_FLTR_LEN 4 (remove) --> sizeof(*h2c)

      * h2c[0] = le32_encode_bits(connect, RTW89_H2C_BCNFLTR_W0_MON_RSSI) -->
        h2c->w0 = le32_encode_bits(connect, RTW89_H2C_BCNFLTR_W0_MON_RSSI)

    - I think this could improve a little more. If anyone have more ideas
      in the future, I will open mind to change them again to make them
      look better.

  - others
    - no change

v3:
  - patch 1/5
    - remove unnecessary type casting
    - use clear style of mask definition for H2C/C2H
  - patch 2/5
    - add comment to describe why polling can help freeing
  - others
    - no change

v2:
  - messed up, please ignore.
