Add driver for SAMA7G5's PDMC

Merge series from Codrin Ciubotariu <codrin.ciubotariu@microchip.com>:

This patch series adds support for Pulse Density Microphone Controller
(PDMC), present on Microchip's SAMA7G5.
The PDMC interfaces up to 4 digital microphones having Pulse Density
Modulated (PDM) outputs. It generates a single clock line and samples 1 or
2 data lines. The signal path includes an audio grade programmable
decimation filter and outputs 24-bit audio words.
The source of each channel can be independently defined as PDMC_DS0 or
PDMC_DS1, sampled at the rising or falling edge of PDMC_CLK.

The patch series starts with a fix on the ASoC DMA engine support. Then
continues with the bindings and the driver of PDMC. It is followed by the
DT nodes for SAMA7G5 and SAMA7G5-EK. In the end, the drivers for PDMC
and PDM microphones are enabled in sama7_defconfig.

Pull sound updates from Takashi Iwai:
"The amount of changes is smaller at this round (what a surprise), but
lots of activity is seen. Most of changes are about ASoC driver
development, especially Intel platforms. Here are some highlights:

General:
- Replace all tasklet usages with other alternatives
- Cleanup of the ASoC error unwinding code
- Fixes for trivial issues caught by static checker
- Spell fixes allover the places

ALSA Core:
- Lockdep fix for control devices
- Fix for potential OSS sequencer mutex stalls

HD-audio and USB-audio:
- SoundBlaster AE-7 support
- Changes in quirk table for the rename handling
- Quirks for HP and ASUS machines, Pioneer DJ DJM-250MK2.

ASoC:
- Lots of updates for Intel SOF and SoundWire enablement
- Replacement of the DSP driver for some older x86 systems; the new
code was written from scratch, better maintenance expected
- Helpers for parsing auxiluary devices from the device tree
- New support for AllWinner A64, Cirrus Logic CS4234, Mediatek MT6359
Microchip S/PDIF TX and RX controllers, Realtek RT1015P, and Texas

ASoC: Updates for v5.10

Not a huge amount going on in the core for ASoC this time but quite a
lot of driver activity, especially for the Intel platforms:

- Replacement of the DSP driver for some older x86 systems with a new
one which was written with closer reference to the DSP firmware so
should hopefully be more robust and maintainable.
- A big batch of static checker and other fixes for the rest of the x86
DSP drivers.
- Cleanup of the error unwinding code from Morimoto-san, hopefully
making it more robust.
- Helpers for parsing auxiluary devices from the device tree from
Stephan Gerhold.
- New support for AllWinner A64, Cirrus Logic CS4234, Mediatek MT6359
Microchip S/PDIF TX and RX controllers, Realtek RT1015P, and Texas

The Sony/Philips Digital Interface Receiver (SPDIFRX) is a serial port
compliant with the IEC-60958 standard. Among its caracteristics, we
mention the following:
- SPDIF/AES-EBU Compatible Serial Port
- 32 Samples FIFO
- Data Width Configurable to 24 bits, 20 bits or 16 bits
- Packed and Unpacked Data Support for System Memory Optimization
- Line State Events Report and Source of Interrupt
- Line Error Rate Report
- Full Memory Map of 192 bits for Channel 1 and Channel 2 Status and
User Data
- First 32-bit Status A, Status B Change Report and Source of Interrupt
- Line Digital Filter
- Register Write Protection
- Abnormal Software Access and Internal Sequencer Integrity Check Reports

This interface is available in Microchip's SAMA7G5 SoC.
