[PATCH 4/5] ARM: at91: sam9_smc: register driver earlier

The driver probe only depends on the device's resources, so there is no
need to delay registration to coredevice_platform_driver. The way the
AT91 code is structured is that:
- board code adds SMC device (not probed from DT, so no deep probe)
- SMC driver probe runs and stores regions
- board code calls into SMC driver to apply config to regions
- board code registers NAND
Failure to keep this order results either in non-functional NAND
or crash. Take the easy way out.
