arm64: dts: allwinner: a64: Fix up RTC device node and clock references

The RTC module on the A64 was claimed to be the same as on the A31, when
in fact it is not. It is actually compatible to the H3's RTC. The A64's
RTC has some extra crypto-related registers which the H3's does not, but
the exact function of these is not clear.

This patch fixes the compatible string and clock properties to conform
to the updated bindings. The device node for the internal oscillator is
removed, as it is internalized into the RTC device. Clock references to
the IOSC and LOSC are also fixed.

arm64: dts: allwinner: a64: add nodes necessary for analog sound support

Add nodes for i2s, digital and analog parts of audiocodec on A64.

The routing paths listed are entries connecting the digital and analog
side of the audio codec together. Due to how device tree works, these
must be copied over to each board device tree, in addition to any board
level routes.

The oversampling rate is set to 128, so that when playing back 192 kHz
audio samples, the MCLK runs at the same rate as the module clock, at
24.576 MHz.

The user manual suggests using different oversampling rates for different
sample rates, but that's not possible without a platform-specific machine
driver.

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.

arm64: dts: allwinner: a64: Add PWM controllers

The Allwinner A64 SoC features two PWM controllers, which are fully
compatible to the one used in the A13 and H3 chips.

Add the nodes for the devices (one for the "normal" PWM, the other for
the one in the CPUS domain) and the pins their outputs are connected to.

On the A64 the "normal" PWM is muxed together with one of the MDIO pins
used to communicate with the Ethernet PHY, so it won't be usable on many
boards. But the Pinebook laptop uses this pin for controlling the LCD
backlight.

On Pine64 the CPUS PWM pin however is routed to the "RPi2" header,
at the same location as the PWM pin on the RaspberryPi.

Tested on Pinebook and Teres-I
