Ivan Grokhotkov 64bce3ce59 freertos: place uxTopUsedPriority into DRAM
When debugging crashes caused by flash cache access errors, OpenOCD may
request the value of uxTopUsedPriority when cache is disabled. Placing
it into IRAM to avoid an error in such case.

/*
* Since at least FreeRTOS V7.5.3 uxTopUsedPriority is no longer
* present in the kernel, so it has to be supplied by other means for
* OpenOCD's threads awareness.
*
* Add this file to your project, and, if you're using --gc-sections,
* ``--undefined=uxTopUsedPriority'' (or
* ``-Wl,--undefined=uxTopUsedPriority'' when using gcc for final
* linking) to your LDFLAGS; same with all the other symbols you need.
