net: dwc_eth_qos: Add DM CLK support for i.MX8M Plus
The DWMAC clock in i.MX8M Plus were so far configured via ad-hoc
architecture code. Replace that with DM clock instead. This way,
the driver claims all its required clock, enables and disables
them, and even gets the CSR clock rate and sets the TX clock rate,
without any need of architecture specific register fiddling. Drop
the architecture specific code while at it too.
The adjustment here is modeled after STM32MP15xx clock handling
in this driver.

net: dwc_eth_qos: Set DMA_MODE SWR bit to reset the MAC
The driver currently only waits for DMA_MODE SWR bit to clear itself.
This is insufficient e.g. on i.MX8M Plus, where the MAC must be reset
before IOMUX GPR[1] content is latched into the MAC and used. Without
the proper reset, the i.MX8M Plus MAC variant does not take the value
in IOMUX GPR[1] into account, which makes it impossible e.g. to switch
interface mode from RGMII to any other.
Since proper reset is desired in general to put the block into defined
state, always assert the DMA_MODE SWR bit before waiting for the bit
to clear itself.

net: dwc_eth_qos: Drop unused dm_gpio_free() on STM32
The dm_gpio_free() is never called, because for stm32, the phy_reset_gpio
pointer is never valid. This is because only tegra186 ever claims the
phy_reset_gpio, all other platforms use the PHY framework to reset the
PHY instead. Drop the dm_gpio_free() and dm_gpio_is_valid().
