usb: renesas_usbhs: replace udelay() with usleep_range()

Browse source

According to Documentation/timers/timers-howto.txt, a driver should
use usleep_range() instead of udelay() on NON-ATOMIC CONTEXT if
"SLEEPING FOR ~USECS OR SMALL MSECS ( 10us - 20ms)".

Since the .hardware_init() and .power_ctrl() will run on NON-ATOMIC
CONTEXT, this patch replaces udelay() with usleep_range().
