Touch Fixes. Deprecate Console
Touch:
- Move defines that may be altered by the touch config file to the lld
header file.
- Move the definition of the Touch driver structure to the lld config
file.
- Changed CONVERSIONS macro to TOUCHSCREEN_CONVERSIONS
- Replaced references to GDISP_SCREEN_WIDTH with gdispGetWidth
- Renamed TOUCHSCREEN_HAS_IRQ to TOUCHSCREEN_HAS_PRESSED to match new
function name.
- Added prototypes for calibration storage functions to
touchscreen_lld.h so that either the lld driver or the application can
define the function.
Console:
-Deprecated into "old" directory. Functionality replaced by gwin.
