[PATCH v2 0/2] Meson8 USB PHY support

The USB2 PHY in the Meson8 SoCs is identical to the one in the Meson8b
and GXBB SoCs.
This series adds a new compatible string for Meson8 and adjusts the
Kconfig and MODULE_DESCRIPTION documentation as well as the dt-bindings
accordingly.

With some additional work the same driver could be used to add USB2
support to Meson6 SoCs as well. However, due to lack of a clock
controller driver for Meson6 and the lack of a board Meson6 support
is not part of this series (Meson6 uses internal mux and divider clocks
which are provided by the USB2 PHY registers, while the newer SoCs seem
to use an alternative clock called "clk_32k_altsel")


Changes since v1:
- split the dt-bindings and the driver changes into separate patches
- rebased to apply on top of my other series "Meson GXL USB2 PHY driver"
  (from [0]) which means that this also applies on top of "phy: Group
  vendor specific phy drivers"
- also update the Kconfig option name (instead of just the description)
