Patch to spi_stm32.c and to ChangeLog

This patch introduces possibility to retrieve and to set the clock rate for
stm32 spi device.

It is valid for stm32 variant, but since it is not possible to chose a variant
in Hardware field, the only supported platform, stm3210e-eval, is chosen.
Please note that the stm3210e-eval's on-board sd card connector is not wired to
spi. If you want to use spi connected sd card with stm3210e-eval, you have to
connect an external sd card connector.

Motivation for this patch came from the need to use SPI connected SD card with
stm32 platform. The SD/MMC protocol starts at low clock rate to read card
properties and eventually switches to highest clock rate allowed. Therefore the
ability to examine and change the clock rate is essential for mmc driver
running on top of spi.
