Various changes to Doxygen structure, to help leaflabs-docs make sense
of everything.

Fix @file in many places. Also fix up the descriptions where it's
appropriate. This standardizes the @file formatting across the library
to explicitly include any parent directories up to the repository
root.
Besides being nice, this will hopefully let us manage Doxygen's XML
output so as to make extracting series-specific pieces via Breathe in
the leaflabs-docs repo possible.

This function has been with us from the earliest days of libmaple.
It's showing its age, as the API it presents is tied to the
STM32F1. Deprecate it, and provide instructions for how to use newer,
more portable APIs. The new way is more verbose, but we can always add
a portable "just set up the PLL, dammit" convenience function later (a
nice candidate is to extract an interface from setup_clocks() in
boards.cpp).

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().

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.

Portions of rcc_clk_enable(), rcc_reset_dev(), and rcc_set_prescaler()
are portable; break these into static inline helpers in
rcc_private.h. These guts of these are portable, but the arrays of
registers etc. are not.
Also add an extern declaration for rcc_dev_table into
rcc_private.h. This lets us put rcc_dev_clk() into a newly resurrected
libmaple/rcc.c, since that's portable.

This is a backwards-compatible change.
Modify libmaple/rules.mk to include the family's include
directory. This allows libmaple/include/libmaple/rcc.h to include the
STM32F1 RCC header with #include <family/rcc.h>. We'll use this
convention henceforth to distinguish between top-level and
family-specific headers.
