The TDM mode using PCM format now has two-bit right shift due to the
format configuration in the driver. According to Figure 4-13 in the
CS53L30 datasheet, using ASP_SCLK_INV = 0 and SHIFT_LEFT = 1 should
be the correct combination to create one-bit right shift for the DSP
type A format.

The maximum slot number of CS53L30 is 4 while it should support
the situation that's less than 4 channels based on the rx_mask.
So when the driver validates the last slot location, it should
check the last active slot instead of always the 4th one.

The codec chip has a physical MUTE pin to let users control it via
GPIO. So this patch add a mute control support to the driver.

The driver is using the set_bias_level to control the power on and
off so it should get SND_SOC_BIAS_OFF in order to proceed normal
powering sequences. This patch enables the idle_bias_off option so
the DAPM core will set the bias level to SND_SOC_BIAS_OFF instead
of stopping at SND_SOC_BIAS_STANDBY.

SND_SOC_DAIFMT_IB_NF = 0x3 (11b) | SND_SOC_DAIFMT_IB_IF = 0x4 (100b)
creates a mask 0x7 (111b) which also includes SND_SOC_DAIFMT_NB_IF
= 0x2 (10b).
So this patch uses the traditional way to check the clock inversion.

When GPIOLIB is disabled, we don't see the declarations from
gpio/consumer.h, so we have to include the header explicitly

CS53L30 is a Quad-Channel ADC from Cirrus Logic with an I2S/TDM DAI.
So this patch adds a codec driver for CS53L30 that includes 4-channel
24-bit recording and TDM mode supports.
