FS#12355 - First patch for HiFiMAN HM-801 target

This is initial patch for HiFiMAN HM-801.
firmware/target/arm/rk27xx/hm60x/lcd-hm60x.c moved to firmware/target/arm/rk27xx/lcd-hifiman.c because all hifimans have same lcd.

HM801 have pcm1704 DAC and hm60x have tda1543. Both this DACs is not configurable, so audio codec is the same.
Thats why this patch rename tda1543.{ch} to dummy_codec.{ch}.

This is rather minor remark but you could use binary search in key reading routine to reduce number of comparisons (look at key driver for MPIO HD200/HD300 for reference). Keys are scanned every 10ms so this is reasonable to optimize this function.
