The USB OTG U3 port may have been disabled early, add support to the
COMBPHY driver to re-enable the U3 port.

This matches changes made in the Linux commit 7bb14b61b7d0 ("phy:
rockchip: naneng-combphy: Enable U3 OTG port for RK3568").

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

The Rockchip TypeC glue driver improperly present itself as a UCLASS_PHY
driver, without ever implementing the required phy_ops.

This is something that in special circumstances can lead to a NULL
pointer dereference followed by a SError crash.

Change the glue driver to use UCLASS_NOP to fix this.

Change to use syscon_regmap_lookup_by_phandle() helper instead of
finding the syscon udevice and making a call to syscon_get_regmap().

No runtime change is expected with this simplication.

The init ops for Rockchip COMBPHY driver is more complex than it needs
to be, e.g. declaring multiple init functions that only differ in the
error message.

Simplify the init ops based on code from the Linux mainline driver.

This change also ensure that errors returned from combphy_cfg() and
reset_deassert_bulk() is propertly propagated to the caller. No other
runtime change is expected with this simplication.

Generic PHY reference counting helps ensure driver ops for init/exit and
power on/off are called at correct state. For this to work the PHY
driver must initialize PHY-id to a persistent value in of_xlate ops.

The Rockchip COMBPHY driver does not initialize the PHY-id field, this
typically lead to use of unshared reference counting among different
struct phy instances.

Initialize the PHY-id in of_xlate ops to ensure use of shared reference
counting among all struct phy instances.

With working shared reference counting for Generic PHY ops there is no
need for the Rockchip USBDP PHY driver to keep its own status (reference
counting) handling.

Simplify the init ops now that shared reference counting is working.
This also removes the unused mode_change handling as part of the
simplication.

No runtime change is expected with this simplication.
