In preparation for multi-OMAP2 kernels, split mach-omap2/clock2xxx_data.c into mach-omap2/clock2420_data.c and mach-omap2/clock2430_data.c. 2430 uses a different device space physical memory layout than past or future OMAPs, and we use a different virtual memory layout as well, which causes trouble for architecture-level code/data that tries to support both. We tried using offsets from the virtual base last year, but those patches never made it upstream; so after some discussion with Tony about the best all-around approach, we'll just grit our teeth and duplicate the structures. The maintenance advantages of a single kernel config that can compile and boot on OMAP2, 3, and 4 platforms are simply too compelling. This approach does have some nice benefits beyond multi-OMAP 2 kernel support. The runtime size of OMAP2420-specific and OMAP2430-specific kernels is smaller, since unused clocks for the other OMAP2 chip will no longer be compiled in. (At some point we will mark the clock data __initdata and allocate it during registration, which will eliminate the runtime memory advantage.) It also makes the clock trees slightly easier to read, since 2420-specific and 2430-specific clocks are no longer mixed together. This patch also splits 2430-specific clock code into its own file, mach-omap2/clock2430.c, which is only compiled in for 2430 builds - mostly for organizational clarity. While here, fix a bug in the OMAP2430 clock tree: "emul_ck" was incorrectly marked as being 2420-only, when actually it is present on both OMAP2420 and OMAP2430. Thanks to Tony for some good discussions about how to approach this problem.
