[PATCH 01/13] MIPS: BCM63XX: add USB host clock enable delay

[Florian Fainelli <florian@openwrt.org>]

Knowledge of the clock setup delay should remain at the clock level (so
it can be clock specific and CPU specific). Add the 100 milliseconds
required clock delay for the USB host clock when it gets enabled.
