Subject: [PATCH v4 00/25] firmware: xilinx: Add xilinx specific sysfs interface

This patch series adds xilinx specific sysfs interface for below
purposes:
- Register access
- Set shutdown scope
- Set boot health status bit

Also this patch series removes eemi ops and adds API
corresponding to each eemi ops.
