From: Ronak Jain <ronak.jain@xilinx.com>

Add new APIs in firmware to configure SD/GEM registers. Internally
it calls PM IOCTL for below SD/GEM register configuration:
- SD/EMMC select
- SD slot type
- SD base clock
- SD 8 bit support
- SD fixed config
- GEM SGMII Mode
- GEM fixed config

You have spaces after "Return:", doesn't match with tabs that you have
after variable documentation.

Ok, will fix the return indentation to tab to match with variable documentation.
