Introduce alternative TRX switching using dedicated timers and peripheral interconnect. This will enable the possibility to independently configure the Tx and Rx settings between the tIFS. Note, this will also provide the opportunity to design a soft realtime Radio ISR. Signed-off-by: Vinayak Kariappa Chettimada <vich@nordicsemi.no>

The current implementation of stm32_gpio_set() uses the GPIO output data register to change the state of individual GPIOs. The generated assembler needs at least 3 instructions: load / modify / store. This opens a small race window, for example if a thread and an interrupt both try to change the state of the same GPIO bank. Use the GPIO bit set/reset register to perform the atomic change without locking. This also has the benefit of a more optimised implementation, which can be useful for GPIO-intensive work.

- Shouldn't freak out if someone passes "main-intel" as the base branch. So make it not freak out; rather accept either "main" OR "main-intel" and all is well with the world. Signed-off-by: Connor Graydon <connor.graydon@intel.com>
