The patch adds initialization of FIQ related handlers to the Amstrad Delta
videophone board code. FIQ will be used instead of a traditional IRQ for
processing all MPU GPIO generated interrupts, including a keyboard serial
clock line.
Amstrad Delta defconfig is modified to use FIQ by default.
Compiles and works on top of patch 2/5: omap1: Amstrad Delta: add a handler
for processing interrupts generated by the FIQ routine
Created and tested against linux-omap for-next,
commit 82f1d8f22f2c65e70206e40a6f17688bf64a892c dated 2009-12-02.
