        src/sys/dev/ic: hd44780_subr.c hd44780_subr.h

Log Message:
Various improvements for connecting HD44780s using bit-banging style devices

o add sc_writereg and sc_readreg functions that get passed the hd44780_chip
  struct and RS (register-select) signal
o add sc_dev to struct hd44780_chip so upper level read/write routines can get
  back to their parent softc
o change TIMEOUT_XXX to HD_TIMEOUT_XXX
o remove sc_rread and sc_rwrite in favor of new sc_writereg and sc_readreg
o add new flag HD_UP to sc_flags that is set once 4bit/8bit mode selection
  has been finalized.
o remove sc_irwrite, MD readreg/writereg should check state of HD_UP instead
