net/irda: convert au1k_ir to platform driver.

Browse Source 
Moderate driver cleanup:
convert to platform driver, get rid of board-specific code.

Driver loads and runs on a DB1100 board.  But since I have no other
IrDA hardware to exchange data with I can't say whether it really sends
and receives.
