Move evdev_ev_kbd_event() helper from evdev to kbd.c as otherwise evdev
unconditionally requires all keyboard and console stuff to be compiled
into the kernel. This dependency happens as evdev_ev_kbd_event() helper
references kbdsw global variable defined in kbd.c through use of
kbdd_ioctl() macro.
While here make all keyboard drivers respect evdev_rcpt_mask while setting
typematic rate and LEDs with evdev interface.
