Ashish Chavan 3cb81651d0 ASoC: da7210: Minor improvements and a bugfix 
This patch improves playback quality for few sample rates like 8000 and
11025 Hz.

This also fixes an issue observed during testing of pll slave mode. Due
to the issue, on some rare occasions there was no sound output for first
time playback after system boot, though all subsequent playbacks were
fine. It was mainly because of the sequence in which SRM bit was
enabled.

* For DA7210 codec, there are two ways to enable/disable analog IOs
* and ADC/DAC,
* (1) Using "Enable Bit" of register associated with that IO
* (or ADC/DAC)
* e.g. Mic Left can be enabled using bit 7 of MIC_L(0x7) reg
*
* (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register
* e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5)
*
* Out of these two methods, the one using STANDBY bits is preferred
* way to enable/disable individual blocks. This is because STANDBY
* registers are part of system controller which allows system power
* up/down in a controlled, pop-free manner. Also, as per application
* note of DA7210, STANDBY register bits are only effective if a
* particular IO (or ADC/DAC) is already enabled using enable/disable
* register bits. Keeping these things in mind, current DAPM
* implementation manipulates only STANDBY bits.
*
* Overall implementation can be outlined as below,
*
* - "Enable bit" of an IO or ADC/DAC is used to enable it in probe()
* - "STANDBY bit" is controlled by DAPM
