arm64: dts: allwinner: drop underscore in node names

Underscores should not be used in node names (dtc with W=2 warns about
them), so replace them with hyphens. Use also generic name for pwrseq
node, because generic naming is favored by Devicetree spec. All the
clocks affected by this change use clock-output-names, so resulting
clock name should not change. Functional impact checked with comparing
before/after DTBs with dtx_diff and fdtdump.

arm64: dts: allwinner: a64: bananapi-m64: Add Bluetooth device node

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, DLDO2 provides
overall power via VBAT, and DLDO4 provides I/O power via VDDIO. The RTC
clock output 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.

arm64: dts: allwinner: a64: Split out data strobe pin from mmc2 pinmux

The eMMC 5.0 standard introduced the data strobe (DS) pin. This pin is
not used for pre-5.0 data modes, nor is it found on pre-5.0 eMMC chips.
On the A64, this pin is muxed with spi0's MISO pin. If the DS pin is
included in the mmc2 pinmux by default, this wil prevent the usage
of both mmc2 and spi0 together.

Instead, split out the DS pin to a separate pinmux that only gets used
by boards that actually have it wired up. Currently supported ones
include the Bananapi M64 and Pine64 Pinebook. These are fixed up.

via GPIO lines, which drive transistors that control current across the

So we set the "default-on" property for it.

The pingroups the GPIO lines belong to require external regulators be
enabled to be able to drive the GPIO high. These regulators also have
other purposes. However the pin controller does not have bindings for
regulators. Here we just set them to always-on.
