abb_inth.c: check all interrupt causes, not just one
The original code used if - else if - else if etc constructs, thus
the first detected interrupt was the only one handled. However,
Iota ITSTATREG is a clear-on-read register, thus if we only handle
the first detected interrupt and skip checking the others, then the
other interrupts will be lost, if more than one interrupt happened
to occur in one ABB interrupt handling cycle - a form of rare race
condition. Change the code to check all interrupts that were read
in this cycle.
