This patch adds the platform file components for the Amstrad Delta LCD
framebuffer. I have confirmed it works with latest git. The patch to
clock.c /is/ needed for this to work.

This #ifdef is not necessary. machine_is_ams_delta() will expand to (0)
when CONFIG_MACH_AMS_DELTA not selected and that if (0) will be
optimized away.

I tend to adopt a belt and braces approach to these things. :) Here's a
revised patch without the #ifdef.

Ok. One last try with this; the id element of ams_delta_lcd_device
should be an int, not a string.
