USB: isp1760: use a write barrier to ensure proper ndelay timing ...
The ISP1760 has some timing requirements where it has to delay a short
period after a write to a register has started. However, this delay is
from the time the write hits the USB chip (the ISP1760), not from the
time where the processor started processing the write. So on a quick
enough processor, it is sometimes possible for the write to not hit the
device before we start delaying, and we then violate the part's timing
requirements, so things stop working.
To avoid all this, insert a write barrier after the register write and
before the timing delay/register read so we can guarantee we only start
counting time after the write has hit the device.
