From: Colin Ian King <colin.king@canonical.com>

When macro PM8001_USE_MSIX is defined there are redundant dead code
calls to pm8001_chip_intx_interrupt_{enable|disable}. Clean this up
by compiling in the appropriate enable/disable handlers for the
defined PM8001_USE_MSIX and undefined PM8001_USE_MSIX cases.
