usb: typec: tcpm: Support multiple capabilities

Browse Source

Refactor tcpm_fw_get_caps to support the multiple pd capabilities got
from fwnode. For backward compatibility, the original single capability
is still applicable. The fetched data is stored in the newly defined
structure "pd_data" and there is an array "pd_list" to store the
pointers to them. A dedicated array "pds" is used to store the handles
of the registered usb_power_delivery instances.

Also implement the .pd_get and .pd_set ops which are introduced in
commit a7cff92f06 ("usb: typec: USB Power Delivery helpers for ports
and partners"). Once the .pd_set is called, the current capability will
be updated and state machine will re-negotiate the power contract if
possible.
