[evb] 45385: - Implement logical keyboard interface. Converts scan code to ASCII codes (just ok). - Implement firmware ConsGetCh based on keyboard interface. - Implement KMI (Keyboard & Mouse Interface) PL050 driver for Versatile to init PS/2 and read keyboard scancodes. Can now press ENTER/whatever when FreeLDR gives "Cannot find freeldr.ini" error. - More fixes

Log:
- Implement logical keyboard interface. Converts scan code to ASCII codes (just ok).
- Implement firmware ConsGetCh based on keyboard interface.
- Implement KMI (Keyboard & Mouse Interface) PL050 driver for Versatile to init PS/2
and read keyboard scancodes. Can now press ENTER/whatever when FreeLDR gives "Cannot
find freeldr.ini" error.
- More fixes
