      API extension for RTC driver.
      Bug fixes for RTC, SPI and UART drivers.

      Unsupported crypto driver compilation error fixed
      GPIO driver API extended with adi_gpio_GroupInterruptPolarityEnable to determine if the interrupts are generated
      on the rising or falling edge of the corresponding GPIO pin.
      RTC driver modified to eliminate the risks of counter overflows.
      RTOS mapping extended with Micrium uC/OS-II.
      UART driver updated for PIO Rx transfers to support all the FIFO trigger levels.

      Further version synchronization across IoT CMSIS Pack products
      Flash controller driver default settings modified to enable ECC.
      New APIs and fixes to drivers
      - FLash driver API extended to support wait states configuration
      - GPIO driver API extended to read group interrupt and output information, and
        to enable/disable increased drive strength capability
      - Fix issues in PWR driver
      - RTC driver API extended with functions to get and clear interrupt status
      - SPI driver API extended with functions to set clock phase and polarity
