Add a variation of RTL8822CS with hci_ver = 0x08. This is fully similar to RTL8822CS with hci_ver = 0x0a
observed on the Tanix TX6 Android set-top box and JetHome JetHub H1.
The controller does not always start when the system starts up, so we do a forced reset via gpio during initialization.
Changes from v3:
- add has_msft_ext option
Changes from v2:
- align the patches for bluetooth-next
Changes from v1:
- remove Signed-off-by chbgdn <[email protected]> as not reachable

Bluetooth: btrtl: Add support for RTL8822C hci_ver 0x08
Bluetooth: hci_h5: Add power reset via gpio in h5_btrtl_open
