From: Bin Meng <bin.m...@windriver.com>
The function selection fields (399:376) should be zeroed out to
prevent leftover from being or'ed into the switch function status
data structure.
This fixes the boot failure as seen in the acceptance testing on
the orangepi target.
Fixes: b638627c723a ("hw/sd: Fix incorrect populated function switch status
data structure")
