[PATCH v3 10/11] target/arm/helper: make it clear the EC field is also in hex

[Alex Bennée]

..just like the rest of the displayed ESR register. Otherwise people
might scratch their heads if a not obviously hex number is displayed
for the EC field.

[PATCH v3 11/11] hw/intc/arm_gic: modernise the DPRINTF

[Alex Bennée]

While I was debugging the icount issues I realised a bunch of the
messages look quite similar. I've fixed this by including __func__ in
the debug print. At the same time I move the a modern if (GATE) style
printf which ensures the compiler can check for format string errors
even if the code gets optimised away in the non-DEBUG_GIC case.
