sparc: Really fix "console=" for serial consoles. If a video head and keyboard are hooked up, specifying "console=ttyS0" or similar to use a serial console will not work properly. The key issue is that we must register all serial console capable devices with register_console(), otherwise the command line specified device won't be found. The sun serial drivers would only register themselves as console devices if the OpenFirmware specified console device node matched. To fix this part we now unconditionally get the serial console register by setting serial_drv->cons always. Secondarily we must not add_preferred_console() using the firmware provided console setting if the user gaven an override on the kernel command line using "console=" The "primary framebuffer" matching logic was always triggering o n openfirmware device node match, make it not when a command line override was given.

fbdev: detect primary display device Add function helper, fb_is_primary_device(). Given struct fb_info, it will return a nonzero value if the device is the primary display. Currently, only the i386 is supported where the function checks for the IORESOURCE_ROM_SHADOW flag.

of: Always use 'struct device.of_node' to get device node pointer. The following structure elements duplicate the information in 'struct device.of_node' and so are being eliminated. This patch makes all readers of these elements use device.of_node instead.
