usb: host: xhci: plat: check hcc_params after add hcd
The commit 4ac53087d6d4 ("usb: xhci: plat: Create both
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 primary hcd.
