Prashant Malani a0ccdc4a77 usb: typec: Add number of altmodes partner attr
Add a user-visible attribute for the number of alternate modes available
in a partner. This allows userspace to determine whether there are any
remaining alternate modes left to be registered by the kernel driver. It
can begin executing any policy state machine after all available
alternate modes have been registered with the connector class framework.

This value is set to "-1" initially, signifying that a valid number of
alternate modes haven't been set for the partner.

Also add a sysfs file which exposes this attribute. The file remains
hidden as long as the attribute value is -1.
