OMAP1: AMS_DELTA: add modem support 

This patch adds support for modem device found on Amstrad E3 (Delta) board.

Based on earlier patch by Jonathan McDowell, available at
http://the.earth.li/pub/e3/2.6.19/ams-delta-modem.patch.
Modified after Ladislav Michl's arch/arm/mach-omap1/board-voiceblue.c.

This patch is dependent on 8250 driver changes getting accepted upstream:
