f8c800e527 Create DSKY Driver Framework 
Added a new driver category for DSKY (Display/Keypad) devices.  Existing DSKY devices were converted into drivers ICM and PKD.  These devices were previously DSKY and DSKYNG.

This removes substantial code duplication and recovers significant space in romldr and dbgmon.

e60bf088c9 DSKY Disk Activity Cleanup 
- The DSKY(ng) can display disk I/O activity as the system runs.  This capability was implemented very erratically.  This update overhauls the mechanism, makes it consistent, and implements it across all disk drivers.

1945c0f52d CBIOS default drive assignment cleanup 
Improved the way that the default drive is assigned in the scenario where you are booting to a ROM-based OS.  This should allow removal of either the RAM drive or the ROM drive without causing unexpected consequences.
