I2S controller on EP93xx seems to have undocumented HW issue. According to
"EP93xx User’s Guide", controller can handle underflow and either transmit
last sample or zeroes in such case until FIFO is filled again. In reality
undeflow conditions seem to confuse internal state machine from time to
time and the whole stream gets shifted by one byte (as captured by logic
analyser on the I2S outputs). One could only hear noise instead of original
stream and this continues until the FIFO is disabled and enabled again.

Work this around by watching underflow interrupt and resetting I2S TX
channel + fill FIFO with zero samples until DMA catches up again. This is
a nasty workaround, but it works. Hence, Kconfig option to disable it in
case of problems.

The driver never supported more than 2 channels because of
ep93xx_i2s_dma_data[] supporting only 1 DMA channel in each
direction.
Stop enabling two unused I2S controller FIFOs, this will simplify
future interrupt support.

On some platforms the platform code may need to add device-properties,
rather then relying only on properties set by the firmware.

This commit moves the parsing of the device-properties from the i2c-driver
probe() function, which may be called at any time, to the component-driver
probe() function, which gets called after the platform code calls
snd_soc_register_card().

This allows the platform code to attach extra device-properties before
the device-properties are parsed.

is_sys_clk_from_pll() is used as a snd_soc_dapm_route.connected callback,
checking RT5640_GBL_CLK to determine if the sys-clk is PLL1 and thus the
PWR_PLL bit in reg PWR_ANLG2 must be set.

RT5640_GBL_CLK is changed by rt5640_set_dai_sysclk(), which gets called by
the pre_pmu / post_pmd functions of the "Platform Clock" dapm-supply.

This creates an ordering issue, during a dapm transition first all
connected() callbacks are called to build a list of supplies to enable
and then the complete list is walked to enable the supplies. Since the
connected() check happens before enabling any supplies,
is_sys_clk_from_pll() ends up deciding if the PWR_PLL bit should be set
based on the state the "Platform Clock" supply had *before* the transition.
This sometimes results in PWR_PLL being off, even though *after* the
transition PLL1 is configured as sys-clk.

This commit removes is_sys_clk_from_pll() instead simply setting / clearing
PWR_PLL in rt5640_set_dai_sysclk() based on the selected sys-clk, which
fixes this and as a bonus results in a nice cleanup.

With the generic dmaengine_pcm support the omap-cpm can be replaced with a
much smaller wrapper.

CPU DAI drivers can use the:
int sdma_pcm_platform_register(struct device *dev,
			       char *txdmachan, char *rxdmachan);

To register the platform driver, txdmachan/rxdmachan is only needed to be
provided if the DMA channel names are not standard tx/rx, like in case of
McPDM, or the DAI is only capable of one audio direction (DMIC, HDMI).

This patch only introduces the source file and changes to the
Kconfig/Makefile, but does not change any of the DAI drivers to use it.
