net: hibmcge: Add irq_info file to debugfs

the driver requested three interrupts: "tx", "rx", "err".
The err interrupt is a summary interrupt. We distinguish
different errors based on the status register and mask.

With "cat /proc/interrupts | grep hibmcge",
we can't distinguish the detailed cause of the error,
so we added this file to debugfs.

the following effects are achieved:
[root@localhost sjj]# cat /sys/kernel/debug/hibmcge/0000\:83\:00.1/irq_info
RX                  : enabled: true , logged: false, count: 0
TX                  : enabled: true , logged: false, count: 0
MAC_MII_FIFO_ERR    : enabled: false, logged: true , count: 0
MAC_PCS_RX_FIFO_ERR : enabled: false, logged: true , count: 0
MAC_PCS_TX_FIFO_ERR : enabled: false, logged: true , count: 0
MAC_APP_RX_FIFO_ERR : enabled: false, logged: true , count: 0
MAC_APP_TX_FIFO_ERR : enabled: false, logged: true , count: 0
SRAM_PARITY_ERR     : enabled: true , logged: true , count: 0
TX_AHB_ERR          : enabled: true , logged: true , count: 0
RX_BUF_AVL          : enabled: true , logged: false, count: 0
REL_BUF_ERR         : enabled: true , logged: true , count: 0
TXCFG_AVL           : enabled: true , logged: false, count: 0
TX_DROP             : enabled: true , logged: false, count: 0
RX_DROP             : enabled: true , logged: false, count: 0
RX_AHB_ERR          : enabled: true , logged: true , count: 0
MAC_FIFO_ERR        : enabled: true , logged: false, count: 0
RBREQ_ERR           : enabled: true , logged: false, count: 0
WE_ERR              : enabled: true , logged: false, count: 0

The irq framework of hibmcge driver also includes tx/rx interrupts.
Therefore, TX and RX are not moved separately form this file.
