MLK-13570-8 usb: chpidea: usbmisc_imx: add non-burst setting for both imx7d and imx7ulp
For all imx Socs later than imx6 (including imx6), the USB_nSBUSCFG.AHBBRST
will be set as 0 at dtsi file, so the non-burst setting needs to be
set at non-core register, or there will be no burst for USB AHB/AXI
transfer.
