[PATCH v7 0/2] Bluetooth: hci_h5: btrtl: Add support for RTL8822CS hci_ver 0x08

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.

While testing the RTL8822CS SDIO WiFi/BT adapter, I found that in some
cases the kernel could not initialize it. However, manually resetting the
adapter via gpio allows it to start correctly.
Apparently at system start the adapter is in an undefined state (including
the unknown state of gpio after starting uboot). A forced reset helps to
initialize the adapter in most cases. Experimentally it was found that
100ms is enough to reset.
So, add power reset via enable-gpios in h5_btrtl_open function.

Changes from v6..v4:
- fix patch description
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 [off-list ref] as not reachable
