Avoid use of the ASoC-specific register I/O functions by converting to
use the MMIO regmap provided the core MFD.

This is slightly more complex than a standard regmap conversion due to
the moderately detailed cache control and the open coding of a register
patch for the class D speaker on the TLV320AIC3007.
Although the device supports paging this is not currently implemented as
the additional pages are only used during the application of the patch
for the TLV320AIC3007.

The registers that are being kept uncached are marked as volatile anyway

As part of a move to remove the duplication of regmap functionality in ASoC
convert the 88pm860x driver to use the regmap from the MFD. This means that
we no longer cache the registers so performance will be slightly reduced
on I/O operations.

The ACPI_PTR() macro evaluates to NULL if ACPI is disabled and hence the
ACPI match table won't be used, causing the compiler to complain. Avoid
this by protecting the table using an #ifdef CONFIG_ACPI.

This patch suppresses calculation of REFCLK parameters when the REFCLK
source frequency is set to zero, additionally it will consider a source
frequency of zero as the REFCLK being disabled and switch to using the
SYNCCLK.

The MC13783 Chip Errata, Rev. 4 says, that depending on SPI clock
and main audio clock speed, the Audio Codec or Stereo DAC do sometimes
not start when programmed to do so. This is due to an internal clock
timing issue related to the loading of the SPI bits into the audio block.
On an i.MX27 based system, this issue lead to switched audio channels under
certain circumstances: RTC + Touch + Audio are used and loaded at startup.
The mentioned workaround of writing registers 40 and 41 two times is implemented
here.
