OS X/Clover patched AppleHDA Realtek ALC Audio

The Clover/kext patched Realtek ALC method enables OS X AppleHDA onboard audio with or without HDMI and DP audio. The script adds codec specific layout and platform files and injects binary patch and pin configuration data to the native installed AppleHDA.kext.

Clover version of Piker Alpha/AppleHDA8Series.sh. The script adds AppleHDA.kext kernel cache patches to config.plist and installs L/E/AppleHDAxxx.kext (xxx = codec)
