Add reset control properties into MDIO nodes.  The 4 MDIO controllers in
AST2600 SOC share one reset control bit SCU50[3].

Please describe the bug being fixed. See stable-kernel-rules.

Thank you for your comment.
The reset deassertion of the MDIO device was usually done by the bootloader (u-boot).
However, one of our clients uses proprietary bootloader and doesn't deassert the MDIO
reset so failed to access the HW in kernel driver.  The reset deassertion is missing in the
kernel driver since it was created, should I add a BugFix for the first commit of this driver?
Or would it be better if I remove " Cc: stable@vger.kernel.org"?

Best regards,
