isp1362_show_regs() is a debugging-only function, with no call sites. It
prints the cached value of the HCuPINTENB register if in_interupt() is
true, otherwise it reads the actual register content.

The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be separated or the context be conveyed in an argument passed by the
caller, which usually knows the context.

Make the conditional based on a function argument.
