This patch adds support for a second and third clock to the usbmisc driver. On
modern freescale ARM cores like the imx51, imx53 and imx6q three clocks ("ahb",
"ipg" and "per") must be enabled in order to access the USB core.

ahb - AMBA High-Performance Bus clock domain
ipg - IP-Bus Gate clock domain
per - Peripheral clock domain

Looks like usbmisc_imx and ci13xxx_imx are growing more and more common
code.
Btw, shouldn't there be a way to specify platform's clock tree
configuration via devicetree or whatnot so that each platform driver
didn't have to request platform specific clocks?
