Add the support for Synopsys HAPS board that uses GMAC5.

In-between the MAC & PHY there can be a mode converter, which converts one
mode to another (e.g. GMII-to-RGMII).
The converter, can be passive (i.e. no driver or OS/SW information
required), so the MAC & PHY need to be configured differently.
For the `stmmac` driver, this is implemented via a `mac-mode` property in
the device-tree, which configures the MAC into a certain mode, and for the
PHY a `phy_interface` field will hold the mode of the PHY. The mode of the
PHY will be passed to the PHY and from there-on it work in a different
mode. If unspecified, the default `phy-mode` will be used for both.

The devicetree binding lists the phy phy as optional. As such, the
driver should not bail out if it can't find a regulator. Instead it
should just skip the remaining regulator related code and continue
on normally.
Skip the remainder of phy_power_on() if a regulator supply isn't
available. This also gets rid of the bogus return code.

tc transparently maps the software priority number to hardware. Update
it to pass the major priority which is what most drivers expect. Update
drivers too so they do not need to lshift the priority field of the
flow_cls_common_offload object. The stmmac driver is an exception, since
this code assumes the tc software priority is fine, therefore, lshift it
just to be conservative.
