To simply porting phy drivers from Linux to U-Boot, define
phy_set_bits() and phy_clear_bits() functions with a similar API to
those used in Linux.
The U-Boot versions of these functions include the `devad` argument
which is not present in the Linux versions, to keep them aligned with
the other phy functions in U-Boot.

Changes v2->v3:
- Documented devad parameter.
Changes v1->v2:
- Split out of series adding RZ/G2L Ethernet support [1]
- Added Marek's Reviewed-by tag
