Pinebook uses RTL8723CS for WiFi and bluetooth. Unfortunately, RTL8723CS
has broken BT-4.1 support, so it requires a quirk.

Add a quirk and wire up 8723CS support in btrtl.
I was asked for a btmon output without the quirk;
however, using the chip without the quirk ends up in a bad state with
"Opcode 0x c77 failed: -56" (HCI_OP_READ_SYNC_TRAIN_PARAMS) on training.
A btmon output with the quirk active was already sent by Vasily.

v1 of this series was sent in July 2020 by Vasily Khoruzhick.
I have tested it to work on the Pinebook.

Changelog:
v2:
   * Rebase
   * Add uart-has-rtscts to device tree as requested by reviewer
v3:
   * Drop the device tree as it was split out and is already integrated.
   * Rename the quirk as requested by reviewer Marcel Holtmann
v4:
   * Use skb_pull_data as requested by reviewer Luiz Augusto von Dentz
v5:
   * Make use of skb_pull_data's length check
v6:
   * Warn on active quirk
