dmaengine: idxd: add event log size sysfs attribute
Add support for changing of the event log size. Event log is a
feature added to DSA 2.0 hardware to improve error reporting.
It supersedes the SWERROR register on DSA 1.0 hardware and hope
to prevent loss of reported errors.
The error log size determines how many error entries supported for
the device. It can be configured by the user via sysfs attribute.
