[dpdk-dev] [PATCH 24/28] raw/cnxk_bphy: add support for interrupt init and cleanup

[Tomasz Duszynski <tduszynski@marvell.com>]

Add support for interrupt initialization and cleanup. Internally
interrupt initialization performs low level setup that allows
custom interrupt handler registration later on.

Interrupt initialization and cleanup are related hence they
are in the same patch.
