RCC: Add new mechanism for configuring the main PLL.
The new style for configuring the PLL is to initialize a (series-specific) struct rcc_pll_cfg, and pass a pointer to it to rcc_configure_pll(). After that's done, you can use rcc_turn_on_clk(RCC_CLK_PLL) to turn on the main PLL, and busy-wait until rcc_is_clk_ready(RCC_CLK_PLL) is true to make sure the new configuration took effect. - libmaple/rcc.h: -- Add struct rcc_pll_cfg, which specifies a PLL configuration. This specifies a PLL source and a void pointer to series-specific PLL configuration data. -- Add rcc_configure_pll(), which takes a pointer to struct rcc_pll_cfg, and configures the main PLL. It's up to each series to define this function. - stm32f1/rcc.h: Add struct stm32f1_rcc_pll_data, to store F1-specific PLL configuration state. - stm32f1/rcc.c: Add an implementation for rcc_configure_pll(). - stm32f2/rcc.h: Add struct stm32f2_rcc_pll_data, to store F2-specific PLL configuration data. - stm32f2/rcc.c: Add an implementation for rcc_configure_pll().
