Add HiFiMAN HM-60x target(s). FS#12319 by Andrew Ryabinin with some (small) modification by me. This also splits rk27xx lcd driver into lcdif-rk27xx and lcd controller specific part. Some modifications to the pcm driver have been made to allow using codecs in slave mode (as TDA1543 used in hifiman is slave only i2s codec).
