Dear Otavio Salvador,
The i.MX23 just one USB port so disable the second controller probe when building for i.MX23.

This is not enough.
For example this portion will do something undefined on mx23:
98 writel(HW_DIGCTL_CTRL_USB0_CLKGATE | HW_DIGCTL_CTRL_USB1_CLKGATE, 99 &digctl_ctrl->reg_clr);
THis ehci-mxs.c needs full review for mx23.
