[ Upstream commit 753a6e17942f6f425ca622e1610625998312ad89 ]
i2sctl register value is set to 0 during hw_free(). This
impacts any ongoing concurrent session on the same i2s
port. As trigger() stop already resets enable bit to 0,
there is no need of explicit hw_free. Removing it to
fix the issue.

The clock names for the two supported codecs are either
"mi2s-*" name variants generated by code. This naming scheme
does not work for platforms like MSM8660 which has I2S channels
named CODEC_I2S_SPKR (rather than just "MI2S tertiary" and other
repetitive names) and consequently have clocks named
"codec-i2s-spkr-osr-clk" and similar.
Skip the runtime generation of clock names and replace it with
name lookup tables encoded into the variant data.

The combination of dev_err() and __func__ make most of these log prints
over 100 chars long. Remove the usage of __func__ to clean the kernel
log and as the usage is not necessary to identify the individual log

Clean up the clock calling code by removing numerous IS_ERR() checks by
just assigning the clock NULL; as this turn all used functions in the
clk API to nops.
Also include the word "optional" in the error message when failing to acquire
the optional osr clocks.

This reverts commit 18560a4e3 (ASoC: qcom: Specify LE device
endianness).
The commit that caused us to specify LE device endianness here,
29bb45f25ff3 (regmap-mmio: Use native endianness for read/write,
2015-10-29), has been reverted in mainline so now when we specify
LE it actively breaks big endian kernels because the byte
swapping in regmap-mmio is incorrect. Let's revert this change
because it will 1) fix the big endian kernels and 2) be redundant
to specify LE because that will become the default soon.

This is a little endian device, but so far we've been relying on
the regmap mmio bus handling this for us without explicitly
stating that fact. After commit 4a98da2164cf (regmap-mmio: Use
native endianness for read/write, 2015-10-29), the regmap mmio
bus will read/write with the __raw_*() IO accessors, instead of
using the readl/writel() APIs that do proper byte swapping for
little endian devices.
So if we're running on a big endian processor and haven't
specified the endianness explicitly in the regmap config or in
DT, we're going to switch from doing little endian byte swapping
to big endian accesses without byte swapping, leading to some
confusing results. Specify the endianness explicitly so that the
regmap core properly byte swaps the accesses for us.

This patch adds support to allow bitclk and osrclk per i2s dai port.
on APQ8016 there are 4 i2s ports each one has its own bit clks.
Without this patch its not possible to support multiple i2s ports in the
lpass driver.

This patch attempts to remove the hardcoded i2s port number in lpass

This will allow other SOCs to use different port numbers on the lpass

This patch tries to make the lpass driver more generic by moving the
ipq806x specific bits out of the cpu and platform driver, also allows the
SOC specific drivers to add the correct register offsets.
This patch also renames the register definition header file into more
generic header file.
