The miscellaneous operation is implemented in BIOS, the kernel can call
_DSM method help to call the implementation in ACPI case. Here is a patch
to do that.

The misc operation for different hw platform may be different, if using
current implementation, it will add a new branch on each function for
every new hw platform, so we add a method for this operation.

Hns-mdio only supports DT case now. do some cleanup to prepare
for introducing other cases later, no functional change.

As device_node is only used by DT case, it is expected to find uniform
ways. So fwnode_handle is the suitable method.

When we use ethtool to retrieves or configure the receive flow hash
indirection table, ethtool needs to call .get_rxnfc to get the ring number
so this patchset implements the .get_rxnfc and fixes the bug that we can
not get the tatal table each time.

As the User Manual describes, maximum value are 9728 for service ports and
1500 for debug ports, not always 9600. So it needs to be configured to
right value for the different port. The max frame len of ppe needs to be
set to the right as well.
