object size
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)

The platform_get_irq_byname() function returns -1 if an error occurs.
zero or positive number on success. platform_get_irq_byname() error
checking for zero is not correct.

On the CPCAP PMIC we can use the ADCs for monitoring the battery,
and there is also a coulomb counter. So let's add basic support for
the battery driver.
I did not add any capacity prediction as that should probably be
done in the user space. Or at least user space should tell the kernel
some battery statistics and then the kernel driver could display the
capacity based on that.
