RXI300 is a HW design to maintain stuffs across BUS, e.g. AXI, AHB, APB.
It will feedback an error when host does an invalid BUS operation.
For example,
* BUS master request without power/clock on.
* host reads/writes/accesses an invalid address.
They might lead to problems such as BUS timeout, platform hang, etc. So,
once if RXI300 feedback an error, it notifies that driver need a L2 SER
(system error recovery) to reset things.
Previously, driver did not parse the error scenario for RXI300. We add
it and assign a corresponding error code which will make SER flow do L2
reset.
