serial: omap: don't access the platform_device
The driver doesn't need to know about its platform_device. Everything the driver needs can be done through the struct device pointer. In case we need to use the OMAP-specific PM function pointers, those can make sure to find the device's platform_device pointer so they can find the struct omap_device through pdev->archdata field.
