usb: phy: mxs: use readl(), writel() instead of the _relaxed() versions

Browse Source 
This patch converts the mxs-phy driver from readl_relaxed(), writel_relaxed()
to the plain readl(), writel() functions, which are available on all platforms.

This is done to enable compile time testing on non ARM platforms.
