[fireball] 39856: - Move part of the 1st stage pnp hacks to kbdclass driver. Previously, the driver (i8042prt) relied on kbdclass's normal reinit routine being called BEFORE a registered boot reinit routine, which is certainly wrong on a real NT system. - Now, the correct order is ensured, and it is not relying on a broken reinit calling order in ReactOS anymore.

Log:
- Move part of the 1st stage pnp hacks to kbdclass driver. Previously, the driver
(i8042prt) relied on kbdclass's normal reinit routine being called BEFORE a registered
boot reinit routine, which is certainly wrong on a real NT system.
- Now, the correct order is ensured, and it is not relying on a broken reinit calling
order in ReactOS anymore.
