ipq6018: usb: Skip usb deinit in emulation

Browse source 
In emulation, during full boot chain, usb clocks are
disabled during usb deinit in uboot. In kernel,
we are using dummy clock driver for emulation.
In order for the usb clocks to be enabled while
kernel boot up, skipped usb deinit in uboot.
