Huacai Chen 35586a77f4 USB: pci-quirks: Fix HCCPARAMS register error for LS7A EHCI 
LS7A EHCI controller doesn't have extended capabilities, so the EECP
(EHCI Extended Capabilities Pointer) field of HCCPARAMS register should
be 0x0, but it reads as 0xa0 now. This is a hardware flaw and will be
fixed in future, now just clear the EECP field to avoid error messages
on boot:
