davinci: Move serial platform_device into SoC-specific files
Currently, there is one set of platform_device and platform_data structures for all DaVinci SoCs. The differences in the data between the various SoCs is handled by davinci_serial_init() by checking the SoC type. However, as new SoCs appear, this routine will become more & more cluttered. To clean up the routine and make it easier to add support for new SoCs, move the platform_device and platform_data structures into the SoC-specific code and use the SoC infrastructure to provide access to the data. In the process, fix a bug where the wrong irq is used for uart2 of the dm646x. Signed-off-by: Mark A. Greer <mgreer@mvista.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
