Xu Yang 12e6ac69cc usb: chipidea: add workaround for chipidea PEC bug 
Some NXP processors using ChipIdea USB IP have a bug when frame babble is
detected.

Issue description:
In USB camera test, our controller is host in HS mode. In ISOC IN, when
device sends data across the micro frame, it causes the babble in host
controller. This will clear the PE bit. In spec, it also requires to set
the PEC bit and then set the PCI bit. Without the PCI interrupt, the
software does not know the PE is cleared.

This will add a flag CI_HDRC_HAS_PORTSC_PEC_MISSED to some impacted
platform datas. And the ehci host driver will assert PEC by SW when
specific conditions are satisfied.
