1. boards/common/qn908x: Compute the image checksum …

   QN908X CPUs require the image to have a valid checksum. The checksum is
   a simple addition of the first 7 uint32_t values stored in the 8th
   position of the image header. This position is a reseved entry of the
   Cortex-M Vector Table and its value depends on other fields that are
   computed at link time. Performing this checksum at link time seems
   hard to do, so instead this patch uses a python script to patch the
   checksum from the ELF file. This redefines the value of FLASHFILE
   to the new .elf file with the checksum fixed.
   
   With this patch, OpenOCD can program and verify QN908X images since
   now they have a valid checksum value.
