Ivan Grokhotkov 845bbc293a freertos: use xTaskQueueMutex to protect tick count ...

Having two different spinlocks is problematic due to possibly
different order in which the locks will be taken. Changing the order
would require significant restructuring of kernel code which is
undesirable.

An additional place where taking xTickCountMutex was needed was in
vApplicationSleep function. Not taking xTickCountMutex resulted in
other CPU sometimes possibly advancing tick count while light sleep
entry/exit was happening. Taking xTickCountMutex in addition to
xTaskQueueMutex has shown a problem that in different code paths,
these two spinlocks could be taken in different order, leading to
(unlikely, but possible) deadlocks.

portmux_impl.h

Especially when internal memory fills up, some FreeRTOS structures (queues etc) get allocated in psram. These structures also contain a spinlock, which needs an atomic-compare-swap operation to work. The psram hardware, however, does not support this operation. As a workaround, this patch detects these spinlocks and will, instead of S32C1I, use equivalent C-code to simulate the behaviour, with an (internal) mux for atomicity.
