Dragan Cvetic cc538f609d misc: xilinx_sdfec: Support poll file operation
Support monitoring and detecting the SD-FEC error events
through IRQ and poll file operation.

The SD-FEC device can detect one-error or multi-error events.
An error triggers an interrupt which creates and run the ONE_SHOT
IRQ thread.
The ONE_SHOT IRQ thread detects type of error and pass that
information to the poll function.
The file_operation callback poll(), collects the events and
updates the statistics accordingly.
The function poll blocks() on waiting queue which can be
unblocked by ONE_SHOT IRQ handling thread.

Support SD-FEC interrupt set ioctl callback.
The SD-FEC can detect two type of errors: coding errors (ECC) and
a data interface errors (TLAST).
The errors are  events which can trigger an IRQ if enabled.
The driver can monitor and detect these errors through IRQ.
Also the driver updates the statistical data.
