08aac020ad stm32: rcc: provide async routines for osc checks 
Start providing async routines for all blocking routines, to make it
easier to use libopencm3 in some RTOS environments.  This is not in
anyway intended to be complete, this just covers a single blocking
routine, rcc_wait_for_osc_ready.  Documentation added to the top level,
and provided for all stm32 families.

97d644c4d3 stm32l4: rcc: Add core functions 
Based on STM32L1, and rather a lot of duplication unfortunately.

1755098617 stm32: adc-v2: pull up voltage regulator control. 
L4 and F3 actually have the same bits to write in the same order, but F3 hides
the name of the deep power down bit.  Keep the like that for now, but there's a
standard API for enabling and disabling the regulator.

697c975dde stm32l4: adc: Initial support for the adc-v2 periph 
Now that there's an adc-v2 peripheral layer, we can just use it straight away
for L4.

f14c678ccb stm32l4: add gpio support 
Just the basic core common functionality gained for free by being a common
peripheral.  Enough for a miniblink.

Fixes some errors in the GPIO memory map.  ST's naming of AHB2 vs AHB3 is
confusing.

507c184456 stm32l4: initial memorymap and vector support 
Values from RM0351rev1, with the correction of the duplicate TIM1_CC entry.

Only stub support so far, but this opens up the beginning of build testing.
