Don't populate the array cpcap_battery_irqs on the stack but instead
make it static. Makes the object code smaller by 99 bytes:
Before:
text data bss dec hex filename
13673 2448 0 16121 3ef9 cpcap-battery.o
After:
text data bss dec hex filename
13510 2512 0 16022 3e96 cpcap-battery.o
(gcc version 8.2.0 x86_64)
