msm8960-common: General cleanup

 * Remove BOARD_HAVE_SAMSUNG_AUDIO - not used in alsa_sound
 * Remove qwerty files - duplicates of AOSP versions (I guess most of
   the Vendor*.kl files can be removed too, as some of these are also
   just copies of AOSP ones)
 * Remove accelerometer/compass feature files - handheld_core_hardware.xml
   already defines these.
 * Clean up leading white space
 * Change some files permissions from 755 to 644
