gl3590: Add method for querying UFP connection power capabilities
GL3590's registers allow to gather information about host connection,
e.g. available power. This may be used by platforms which are powered by
hub's UFP.
Add missing license headers.
BUG=b:144776402
BRANCH=main
TEST=With consecutive patch applied, verify that available input power
reported by servo_v4p1 is correct.
