scripts: dts: gen_defines: Generate interrupt-controller macro
Extend the gen_defines.py write_interrupts(node) function to
generate macros to get the interrupt controller for an
interrupt specifier by idx and by name.
The information is already generated by edtlib.py and stored in
node.interrupts[].controller. This addition uses the node pointed
to by the controller member to generate the following example output
define DT_N_S_device1_IRQ_IDX_0_CONTROLLER \
DT_N_S_gpio_800
define DT_N_S_device1_IRQ_NAME_test4_CONTROLLER \
N_S_device1_IRQ_IDX_0_CONTROLLER
