ALSA: hda - Fix LED GPIO setup for HP laptops with IDT codecs

This patch fixes an error in processing of the HP BIOS configuration to enable
GPIO based mute LED indicator control. That error causes driver to enable
such control on all HP systems with the 92HD75 IDT codecs and results in
unnecessary toggling of the GPIO on mute control manipulation.

It also adds support of the future HP BIOS configuration extension for the
named control. New configuration string has a format HP_Mute_LED_P_G
where P can be 0 or 1 and defines mute LED GPIO control state (low/high)
that corresponds to the NOT muted state of the master volume
and G is the index of the GPIO to use (0..9)

Lastly, it adds more systems to the support of the audio implementation
as found on HP B-series systems
