[Qemu-ppc] [PATCH] ps2kbd: default to scan enabled after reset

[Hervé Poussineau]

A check for scan_enabled has been added to ps2_keyboard_event in commit
143c04c7e0639e53086519592ead15d2556bfbf2 to prevent stream corruption.
This works well as long as operating system is resetting keyboard, or enabling 
it.

This fixes IBM 40p firmware, which doesn't bother sending KBD_CMD_RESET,
KBD_CMD_ENABLE or KBD_CMD_RESET_ENABLE before trying to use the keyboard.
