net: dsa: bcm_sf2: Restore CFP rules during system resume
The hardware can lose its context during system suspend, and depending
on the switch generation (7445 vs. 7278), while the rules are still
there, they will have their valid bit cleared (because that's the
fastest way for the HW to reset things). Just make sure we re-apply them
coming back from resume. The 7445 switch is an older version of the core
that has some quirky RAM technology requiring a delete then re-inser to
guarantee the RAM entries are properly latched.
