USB: OHCI: ohci-pxa27x: remove useless functions

The ohci_hcd_pxa27x_drv_probe function is not doing anything other
than calling usb_hcd_pxa27x_probe function so ohci_hcd_pxa27x_drv_probe
function is useless that is why removed ohci_hcd_pxa27x_drv_probe
function and renamed usb_hcd_pxa27x_probe function to
ohci_hcd_pxa27x_drv_probe for proper naming.

The ohci_hcd_pxa27x_remove function is also not doing anything other than
calling usb_hcd_pxa27x_remove that is why removed ohci_hcd_pxa27x_remove
function and renamed usb_hcd_pxa27x_remove to ohci_hcd_pxa27x_remove for
proper naming.
