RCC: Clean up and sanitize interfaces across F1, F2 series.
Additions: - rcc_switch_sysclk(): For changing the clock used as SYSCLK's source. - enum rcc_clk: One for each system and secondary clock source (e.g. HSE, LSE). These are defined on a per-series basis in each of the <series/rcc.h>. - rcc_turn_on_clk(), rcc_turn_off_clk(), rcc_is_clk_ready(): For turning on system and secondary clock sources, and checking whether or not they're ready. Uses enum rcc_clk. Removals: - rcc_clk_init(): There's no way to port this to F2. Move it to the F1 header. This also means we can remove the empty implementation and enum rcc_pll_multiplier from the F2 RCC header, where it doesn't make any sense. Also fix up some includes, and rewrite rcc_clk_init() in terms of the new clock source management functions. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
