Recent changes in the stmmac driver, it removes the phy_reset hook
from struct stmmac_mdio_bus_data by commit <fead5b1b5838ba2>, and
add the member of needs_reset to struct stmmac_mdio_bus_data by
commit <1a981c0586c0387>.

For MDIO bus The we have:

struct stmmac_mdio_bus_data {
- int (*phy_reset)(void *priv);
unsigned int phy_mask;
int *irqs;
int probed_phy_irq;
+ bool needs_reset;
};

Where:
- o phy_reset: hook to reset the phy device attached to the bus.
o phy_mask: phy mask passed when register the MDIO bus within the driver.
o irqs: list of IRQs, one per PHY.
o probed_phy_irq: if irqs is NULL, use this for probed PHY.
+ o needs_reset: make MDIO bus reset optional.

For DMA engine we have the following internal fields that should be
tuned according to the HW capabilities.
