Add Synopsys eDMA IP version 0 debugfs support to assist any debug
in the future.
Creates a file system structure composed by folders and files that mimic
the IP register map (this files are read only) to ease any debug.
To enable this feature is necessary to select DEBUG_FS option on kernel
configuration.
Small output example:
(eDMA IP version 0, unroll, 1 write + 1 read channels)
% mount -t debugfs none /sys/kernel/debug/
% tree /sys/kernel/debug/dw-edma-core:0/
