Removing unnecessary ThirdParty ports -- Wiced_CY and nrf52840-dk.

Browse Source 
For projects depending on either of these two ports, please update your projects according to below:
Wiced_CY -- Use GCC/ARM_CRx_No_GIC instead. 
nrf52840-dk -- Use GCC/ARM_CM7/r0p1 instead. Please note that, kernel port shall only take dependency on MCU core, not MCU peripherals. (Please take out RTC related from kernel port.) For low power feature (tickless) in FreeRTOS, please follow this page https://www.freertos.org/low-power-ARM-cortex-rtos.html. In case ARM_CM7/rop1 is missing any feature, reach out to us.
