To avoid the actual PLL settings to differ from the state expected by
the clock driver, the codec should only be fully reset before the clocks
are registered. But we also need to ensure that the software reset
happens at all before clock registration, as not all boards have a reset
GPIO.
Move the software reset from aic32x4_component_probe() to
aic32x4_probe() and reorder the reset and registration sequence:
1. Reset via GPIO (if available)
2. Reset via software
3. Register component
4. Register clocks
Note that aic32x4_component_probe() is only called after aic32x4_probe()
has finished, so the reset in aic32x4_component_probe() was happening too
late.

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING
Correct the interrupt flags, assuming the author of the code wanted some
logical behavior behind the name "ACTIVE_xxx", this is:

Fix the BCLK inversion for DSP modes
This is how it is defined by ASoC:
* BCLK:
* - "normal" polarity means signal is available at rising edge of BCLK
* - "inverted" polarity means signal is available at falling edge of BCLK
The adcx140 defines the BCLK edge based on coding type.
The PCM (DSP_A/B) should drive on rising and sample on falling edge, so
from ASoC pov, it is IB_NF. But from the codec pov if it is configured in
DSP mode, then the BCLK should not be inverted, defaults to the coding
standard.
For i2s, it is NB_NF from ASoC pov (drive on falling, sample on rising).
>From the codec's pov BCLK should not invert either, as this is the default
for the coding.
So, inversion must take the format into account:
IB_NF + DSP_A/B == the codec bclk inversion should be disabled
NB_NF + DSP_A/B == the codec bclk inversion should be enabled
NB_NF + I2S == the codec bclk inversion should be disabled

When CONFIG_SND_CTL_VALIDATION is set, accesses to extended bytes
control generate spurious error messages when the size exceeds 512
bytes, such as

invalid count 1024
In addition the error check returns -EINVAL which has the nasty side
effect of preventing applications accessing controls from working,
e.g.
root@plb:~# alsamixer
cannot load mixer controls: Invalid argument
It's agreed that the control interface has been abused since 2014, but
forcing a check should not prevent existing solutions from working.
This patch skips the checks conditionally if CONFIG_SND_CTL_VALIDATION
is set and the byte array provided by topology is > 512. This
preserves the checks for all other cases.
