MLK-12530 ehci: Fix OTG ID detection issue on mx7
There are two problems in EHCI driver for mx7, and cause the OTG ID detection
failed to work.
1. The offset for phy_status register in usbnc_regs is not correct.
2. We should clear the USBNC_PHYCFG2_ACAENB bit to enable the OTG ID detection,
not set it. When the bit is set, the ACA Resistance Detection is enabled,
which disables the OTG ID detection, because the internal pull up is off.
