ice: Support VF queue rate limit and quanta size configuration
Add support to configure VF queue rate limit and quanta size.
For quanta size configuration, the quanta profiles are divided evenly
by PF numbers. For each port, the first quanta profile is reserved for
default. When VF is asked to set queue quanta size, PF will search for
an available profile, change the fields and assigned this profile to the
queue.
