Jonas Jelonek 51992c87c8 kernel: rtl8261n: add post-reset MDIO stabilization delay
After the RTL8261N asserts a reset, the MDIO bus becomes temporarily
unavailable during the chip's reinitialization sequence. Any subsequent
read or write issued before the PHY has stabilized will fail.

Add a 30ms delay after triggering the reset to ensure the chip is reachable
via MDIO before resuming communication.
