usb: xhci-plat: check hcc_params after add hcd

HCDs before adding them") move add hcd to the end of
probe, this cause hcc_params uninitiated, because xHCI
driver sets hcc_params in xhci_gen_setup() called from
usb_add_hcd().

This patch checks the Maximum Primary Stream Array Size
in the hcc_params register after add hcd.
