[ALSA] hda_proc - Add a number of new settings to proc codec output

This patch adds additional output to the /proc codec#X info.
The following pieces of information are added to the output:
-  Balanced, L/R swap, trigger, impedance sense pin capabilities
-  Vref pin capabilities
-  Current Vref pin widget control setting
-  Default configuration association, sequence, and misc bit test
-  EAPD/BTL bits conveying balanced mode, EAPD, and L/R swap
-  Power state modified to show state name as well as setting vs actual value
-  GPIO parameter output on Audio Function Group, including enumeration of IO
   pins which are indicated present (Any I and O pins are not output at this
   time)
-  Stripe and L/R swap widget capabilities
-  All digital converter bits: enable, validity, validity config, preemphasis,
   copyright, non-audio, professional, generation level, and content category
-  Converter stream and channel values for in/out widgets
-  SDI select value for in widgets
-  Unsolicited response widget capability tag and enabled bit
-  Delay widget capability value
-  Processing widget capability benign bit and number of coefficients
-  Realtek Define Registers: processing coefficient, coefficient index
[Also, fixed space/tab issues and make codes a bit more readable
