cpu/cortex-m: Enable STKALIGN to make the Cortex-M keep the stack 8 byte aligned

[DipSwitch]

This was a part of my effort to fix 1891 but this was not the problem.

Anyhow a nice add. :)

 /* for Cortex-M3 r1p0 and up the STKALIGN option was added, but not automatically
  * enabled until revision r2p0. For 64bit function arguments to work properly this
  * needs to be enabled.

ACK, don't have a cortex m3 r1p0 to test on though.

All stm32f1 others I don't know. :) tested and still worked.
