staging: axis-fifo: add debugfs interface for dumping fifo registers
For debugging purposes, add a simple, read-only debugfs interface to dump
the following fifo registers:
ISR - Interrupt Status Register
IER - Interrupt Enable Register
TDFV - Transmit Data FIFO Vacancy
RDFO - Receive Data FIFO Occupancy
$ cat /sys/kernel/debug/43c00000.axi_fifo_mm_s/regs
