* fix alignment exception for ullPortInterruptNesting. While loading (LDR X5, ullPortInterruptNestingConst) the ullPortInterruptNesting variable, the program control seems to be stuck and there is no abort or stack trace observed (as there is no exception handler is installed to catch unaligned access exception). Program control moves forward, if one just declares this varible to be 2 bytes aligned but then varible is not updated properly. One of my colleague, pointed out that issue is due to the fact that ullPortInterruptNesting must be at 8 bytes aligned address but since "vApplicationIRQHandler" (that has 4 bytes of address) is sitting between two 8 bytes aligned addresses that forces ullPortInterruptNesting to be at 4 byte aligned address, causing all sort of mess. It works on QEMU (on ARM64) as it is, since there is no such check for unaligned access but on real hardware it is prohibited. Workaround to this problem is, either we skip 4 byets (using .align 4) after vApplicationIRQHandler declaration or declare it the end of all declarations. This commit does the latter one.

Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the five sample memory allocators as described on the https://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler, where the directory name denotes the compiler specific files the directory contains. For example, if you are interested in the [compiler] port for the [architecture] microcontroller, then the port specific files are contained in FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the only port you are interested in then all the other directories can be ignored.
