STM32/STM32F1 patchset v13

Hi,

I have posted version 13 of the patchset. As usual the series is
avaialable in my github repo https://github.com/bboozzoo/zephyr/ in
branch bboozzoo/stm32f10x-for-upstream-v13.

Changelog
=========

- addressed cosmetic comments

- updated pinmux driver to use struct pin_config instead of a custom
wrapper

- added support for HSE (high speed external oscillator) as clock
input for PLL or directly for SYSCLK, this allows for using much
higher SYSCLK values, up to 72MHz

- added register mapping for embedded flash controller; this change is
required by HSE and higher SYSCLK support, as flash access latency
needs to be configured for higher values of system clock

- svc_handler unaligned access fix; I would like to ask ARM experts to
look at this change, by no means I consider myself such expert. The
problem was identified when running latency benchmarks. The
benchmarks enable IRQ offloading, what enables previously unused
code paths in svc_handler. When the code attempts to access svc
parameter (which is not 4 byte aligned), unaligned access exception
occurs.
