Platform: Implement Flash uninitialize function

- This patch introduces an uninitialize function for the QSPI Flash
controller to restore it's default state before passing execution
to runtime image from MCUBoot.
- Implements a basic configuration function for the QSPI Flash
controller and Flash memory that enables operation in single
SPI mode. It is used at the initialization of the Flash controller.
