HAL is built from source from now on.
m7-common: Update thermald
m7-common: Update mpdecision
m4: vendor blobs cleanup

Remove unused firmwares, amp config files, libs for cameras
we don't have, etc.
Some of these files weren't even referenced in the makefile.
m4: Resurrect chromatix libs for other camera sensors

Turns out there are units out there bearing same name/variant/model
numbers having different camera sensors. Play it safe and restore all
chromatix libs shipped by HTC.
