Could you use is_usbotg_phy_active() for this purpose?
Please see:

imx: add macro to detect whether USB PHY is active
This macro allows to detect whether the USB PHY is active. This is helpful to detect if the boot ROM has previously started the USB serial downloader.
The idea is taken from the mfgtool support in the NXP U-Boot: http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/?h=imx_v2016....
