Input: ams_delta_serio: use IRQ resource
The driver still obtains IRQ number from a hardcoded GPIO. Use IRQ
resource instead.
For this to work on Amstrad Delta, add the IRQ resource to
ams-delta-serio platform device structure. Obtain the IRQ number
assigned to "keybrd_clk" GPIO pin from FIQ initialization routine.
As a benefit, the driver no longer needs to include
<mach/board-ams-delta.h>.
