First commit fix error when :
1 - Deactivated eth0 (ip link set eth0 down)
2 - Perform low power procedure
3 - Reactivate eth0 (ip link set eth0 up)
=> eth0: stmmac_hw_setup: DMA engine initialization failed
         stm32-dwmac 5800a000.ethernet eth0: stmmac_open: Hw setup failed

Second commit fix bad cleaning when error during stmmac_mdio_register.

V2: - put Reviewed-by from Russell for second commit.
    - update first commit with Russell'remark.
    - Dropped the third patch from v1. It requires additional work on the
      pinctrl framework to add a new state, and I don’t want this to
      block the other two patches.
      I do not intend to drop this change; I will follow up on it in a
      separate thread together with Antonio Borneo.
