ARM: dts: s5pv210: remove dedicated 'audio-subsystem' node

[ Upstream commit 6c17a2974abf68a58517f75741b15c4aba42b4b8 ]

The 'audio-subsystem' node is an artificial creation, not representing
real hardware.  The hardware is described by its nodes - AUDSS clock
controller and I2S0.

Remove the 'audio-subsystem' node along with its undocumented compatible
to fix dtbs_check warnings like:

  audio-subsystem: $nodename:0: 'audio-subsystem' does not match '^([a-z][a-z0-9\\-]+-bus|bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'
