This patch restrict the usage of extcon_update_state() in the extcon
core because the extcon_update_state() use the bit masking to change

it may occur the probelm with the handling mistake of bit mas

There's still __schedule()->context_switch()->finish_task_switch().

This patch adds the support of the property capability setting. This function
decides the supported properties of each external connector on extcon provider
driver.

This patch removes the usage of extcon_set_state() because it uses the bit
masking to change the state of external connectors. The extcon framework
should handle the state by extcon_set/get_cable_state_() with extcon id.

Relying on PM-ops for shutting down PHY clocks was a
bad idea since the users (e.g. USB DWC3) might not
have been suspended by then.
Get rid of all PM-ops. It is the sole responsibility
of the PHY user to properly turn OFF and de-initialize
the PHY as part of its suspend routin

This patch support the extcon property for the external connector
because each external connector might have the property according to
the H/W design and the specific characteristics.

There is no need for a semi-colon at the end of a switch statement so

Add a PHY provider driver for the rk3399 SoC Type-c PHY. The USB
Type-C PHY is designed to support the USB3 and DP applications.
The USB3 operates in SuperSpeed mode and the DP can operate at RBR,
HBR and HBR2 data rates. This driver create 2 PHY devices separately

The newer SoCs (rk3366, rk3399) take a different usb-phy IP block
than rk3288 and before, and most of phy-related registers are also
different from the past, so a new phy driver is required necessarily.
