usb: typec: ucsi: always register a link to USB PD device

Browse Source 
[ Upstream commit c0f66d78f42353d38b9608c05f211cf0773d93ac ]

UCSI driver will attempt to set a USB PD device only if it was able to
read PDOs from the firmware. This results in suboptimal behaviour, since
the PD device will be created anyway. Move calls to
typec_port_set_usb_power_delivery() out of conditional code and call it
after reading capabilities.
