ramfunc region is copied into RAM from FLASH region during XIP init. We copy from the loadaddr of the region, and were previously loading to the symbol __ramfunc_start. This is incorrect when using an MPU with alignment requirements, as the __ramfunc_start symbol may have padding placed before it in the region. The __ramfunc_start symbol still needs to be aligned in order to be used by the MPU though, so define a new symbol __ramfunc_region_start, and use that symbol when copying the __ramfunc region from FLASH to RAM.
