If the user reinitializes the network interface, the PHY will reinitialize,
and the CKO settings will revert to their initial configuration(be enabled).
To prevent CKO from being re-enabled,
en8811h_clk_restore_context and en8811h_resume were added
to ensure the CKO settings remain correct.

EN8811H outputs 25MHz or 50MHz clocks on CKO, selected by GPIO3.
CKO clock operates continuously from power-up through md32 loading.
Implement clk provider driver so we can disable the clock output in case
it isn't needed, which also helps to reduce EMF noise

'struct mdio_device_id' is not modified in these drivers.
Constifying these structures moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

Setting LED_OFF via brightness_set should deactivate hw control, so make
sure netdev trigger rules also get cleared in that case.
This fixes unwanted restoration of the default netdev trigger rules and
matches the behaviour when using the 'netdev' trigger without any
hardware offloading.

These error paths accidentally return "ret" which is zero/success
instead of the correct error code.

Add the driver for the Airoha EN8811H 2.5 Gigabit PHY. The phy supports
100/1000/2500 Mbps with auto negotiation only.
The driver uses two firmware files, for which updated versions are added to
linux-firmware already.
Note: At phy-address + 8 there is another device on the mdio bus, that
belongs to the EN881H. While the original driver writes to it, Airoha
has confirmed this is not needed. Therefore, communication with this
device is not included in this driver.
