common: overlay: update prefix name for Fe-Pi codec

Browse Source 
Currently we are using random prefix names for widgets and mixer controls.
These are not very descriptive and not consistent across platforms. For
example 40-pin header has prefix "x" on TX2 and "y" on Xavier.

For better readability this patch updates prefix names for above. Following
guideline is proposed to have consistency in the naming:
  1. Shorter prefix is preferrable, at the same time keep it meaningful.
     It should be noted that maximum allowed size, including prefix, for a
     control name is "44" characters.
  2. Prefix is preferred to have an indication about the I/O it sits on and
     the codec it belongs to. If there are multiple instances of the codec
     on the same I/O, these can be differentiated by L/R or A/B/C/... or
     1/2/3... suffix, whichever suits best for the board.
  3. On-board codec can use combination of "CVB" and codec initials. If
     there are multiple instances of the codec then additionally suffix
     mentioned in [2] can be used.
  4. Prefix for 40-pin header is used as "H40". Similarly other I/O ports
     can use similar syntax or specific names can be used to indicate the
     I/O port. One such example would be "M2.E" which is more descriptive
     than just "Hxx".

As per above "H40-SGTL" prefix is used for Fe-Pi card.
