ARM: 7413/1: move read_{boot,persistent}_clock to the architecture level
At the moment, read_persistent_clock is implemented at the platform level, which makes it impossible to compile these platforms in a single kernel. Implement these two functions at the architecture level, and provide a thin registration interface for both read_boot_clock and read_persistent_clock. The two affected platforms (OMAP and Tegra) are converted at the same time.
