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().
