[v2,34/38] cxlflash: Update synchronous interrupt status bits

Commit Message

Uma Krishnan Feb. 26, 2018, 10:24 p.m. UTC

The SISLite specification has been updated to define new synchronous
interrupt status bits. These bits are set by the AFU when a given PASID or
EA is bad and a synchronous interrupt is triggered.

The SISLite header file is updated to support these new bits. Note that
there are also some formatting updates to some of the existing bits to
allow all of the definitions to line up uniformly.
