ARM: imx: fix mx51 ehci setup errors

This patch completes commit 08406f5 by fixing the following issues, according to
the reference manual:
* MXC_OTG_UCTRL_OPM_BIT disables (masks) the power/oc pins if set, like H1PM and
  H2PM, not the opposite.
* MXC_OTG_PHYCTRL_OC_DIS_BIT disables the oc pin if set, like H1_OC_DIS, not the
  opposite.
* Typos in comments.
