posix-timers: Make posix_clocks immutable
There are no more modular users providing a posix clock. The register function is now pointless so the posix clock array can be initialized statically at compile time and the array including the various k_clock structs can be marked 'const'. Inspired by changes in the Grsecurity patch set, but done proper.
