[PATCH] v4l: (935) Moved common IR stuff to ir-common.c

- The pinnacle handler & remote are common to saa7134 PCI boards and em28xx
  USB boards, so the keymap was moved to ir-common and the keyhandler is back
  to ir-kbd-i2c

- request_module("ir-kbd-i2c") is no longer necessary at saa7134-core since
  saa7134.ko now depends on ir-kbd-i2c.ko to get the keyhandler
