This patchset adds support for USB on Amlogic A1 SoCs.

This patchset is composed with :
- bindings of the PHY
- bindings of the USB Control Glue
- PHY Driver
- USB Control Glue driver
- dts of the PHY
- dts of the USB Controller

The Amlogic A1 USB Complex is composed of :
- 1 DWC3 USB controller for USB2 Host functionality
- 1 USB2 PHY for USB2 Host functionality

The USB Control Glue setups the clocks and the reset about DWC3 USB
controller, and binds to the USB2 PHY. It also configures the 8bit
UTMI interfaces for the USB2 PHY, including setting USB2 phy mode.

The USB2 PHY driver initializes the phy analog settings, phy PLL 
setup and phy tuning.

This patchset is based on A1 clock/power domain/reset series at [0].

Changes since v1:[1]
 - integrate glue and phy drivers into g12a's
 
Changes since v2:[2]
 - modify amlogic,meson-g12a-usb-ctrl.yaml with dt_binding_check tool
 - phy/glue driver use of_device_get_match_data to distinguish A1 from G12A

Changes since v3:[3]
 - fix bindings mistakes of the PHY according Rob's comments
 - fix bindings mistakes of the USB Control Glue according Rob's comments
 - phy driver add xtal_usb_phy clock which moved from glue driver
 - glue driver use otg_mode instead of soc_id to support otg function

Changes since v4:[4]
 - phy driver revert reset-names changes
 - phy driver change clock name to "xtal" to consistent with g12a
 - glue driver add drvdata otg_switch_supported
