This adds support for an optional extra interrupt cell to specify edge
vs level triggered. It is backward compatible with dts files with only
one cell, and will default to level-triggered in such a case.

This is useful if you want to build a kernel without a ramfs, or
if you want to test the kernel build without having an initramfs
available at the hardcoded location.

Even after fixing the issue, GCC 4.8 still complains with a warning,
but with the fix, I think it's a false positive. Therefore I have
also added a #pragma to ignore the warning.

Make sure that usecs is casted to long long, to ensure that the
(usecs * 4295 * HZ) multiplication is 64 bit.
Initially, the (usecs * 4295 * HZ) part was done as a 32 bit
multiplication, with the result casted to 64 bit. This led to some bits
falling off.
