Subject: usb: typec: fusb302: Set the current before enabling pullups
This seems more reasonable and should avoid short period of incorrect
current setting being applied to CC pin.

Subject: usb: typec: fusb302: Add OF extcon support
It's possible to create a dependency cycle between fusb302 and
other drivers via extcon device, so we retrieve the device on
demand after probe and not during probe.

Subject: phy: rockchip-typec: Make sure the plug orientation is respected
RK3399 TRM says about bit 8:
typec_conn_dir_sel: TypeC connect direction select
- 0: select typec_conn_dir (bit0 of this register) to TypeC PHY
- 1: select TCPC ouput typec_con_dir to TypeC PHY (default value)
This means that by default, typec_conn_dir bit is not respected.
Fix setting of typec_conn_dir by setting typec_conn_dir to 0 first.
