qong: remove unneeded IOMUX settings

On qong board some of the USBH2 pins are set via GPR register, so don need to setup
the IOMUX for each pin individually.

Other than that, these pins should not be configured as primary function because the primary
function selects SSI functionality.

Let GPR register do the work and remove the unneeded IOMUX setup.
