usb: typec: ucsi: Fix a missing bits to bytes conversion in ucsi_init()

The GET_CAPABILITY size is wrong. The definitions for the
command sizes are for bitfieds and therefore in bits, not
bytes.

This fixes an issue that prevents the interface from being
registered with UCSI versions older than 2.0 because the
command size exceeds the MESSAGE_IN field size.
