Modified FreeRTOS kernel to disable all interrupts prior entry to critical section and enable all interrupts upon exiting from critical section. This kernel behavior is compatible with standard FreeRTOS port to the ARM Cortex-M0 core. All freertos_cfg header files updated to reflect kernel change.
Updated PLL_Disable macro and Quad Timer driver.
Added UART_SetBaudRate macro.
Removed RCM_ClrResetFlags macro.
Fixed issue of generating callback events after conversion for these ADC channels with interrupt disabled.
