The AP6212 is based on the Broadcom BCM43430 or BCM43438. The WiFi side
identifies as BCM43430, while the Bluetooth side identifies as BCM43438.
The Bluetooth side is connected to UART1 in a 4 wire configuration. Same
as the WiFi side, due to being the same chip and package, the board's
fixed 3.3V power regulator provides overall power via VBAT and I/O power
via VDDIO. The RTC clock output from the SoC provides the LPO low power
clock at 32.768 kHz.
This patch enables Bluetooth on this board, and also adds the missing
LPO clock on the WiFi side. There is also a PCM connection for
Bluetooth, but this is not covered here.

Three more variants of the Bananapi M2 Plus have been introduced. One
with the H5 instead of the H3, another with the H2+ instead, and the
last with the H3 but with WiFi and eMMC removed.
All these variants use the same board. This patch splits out the
non-SoC-specific parts of the device tree, so that they can be shared
among all the variants. The original Bananapi M2 Plus has been renamed
to Bananapi M2 Plus H3.
