net: hibmcge: Add interrupt supported in this module

Browse source 
The driver supports four interrupts: TX interrupt, RX interrupt,
mdio interrupt, and error interrupt.

Actually, the driver does not use the mdio interrupt.
Therefore, the driver does not request the mdio interrupt.

The error interrupt distinguishes different error information
by using different masks. To distinguish different errors,
the statistics count is added for each error.

To ensure the consistency of the code process, masks are added for the
TX interrupt and RX interrupt.

This patch implements interrupt request, and provides a
unified entry for the interrupt handler function. However,
the specific interrupt handler function of each interrupt
is not implemented currently.

Because of pcim_enable_device(), the interrupt vector
is already device managed and does not need to be free actively.
