amixer: skip showing asoc tlv byte controls

Browse source 
ASoC TLV Byte controls are very large size controls so we should add new
options for these. So skip dumping contents for these.

$amixer -c0 cget numid=16
numid=16,iface=MIXER,name='mdl params'
  ; type=BYTES,access=-----RW-,values=30336
  ; ASoC TLV Byte control, skipping bytes dump
