[PATCH][Binutils]: Fix range check in ihex PR/24065 for 32 bit hosts.

[Tamar Christina]

Hi All,

The change in PR binutils/24065 added a check to see if the value is in a 32-bit range.
It does this using two 64-bit masks that are stored inside a bfd_vma.

This now rejects all values on a 32-bit host as bfd_vma seems host dependent.  This
patch changes the type for the masks from bfd_vma to uint64_t.
    
build on native hardware and regtested on
  aarch64-none-elf, aarch64-none-elf (32 bit host),
  aarch64-none-linux-gnu, aarch64-none-linux-gnu (32 bit host)
  arm-none-eabi, arm-none-eabi (32 bit host),
  arm-none-linux-gnueabihf, arm-none-linux-gnueabihf (32 bit host)

Cross-compiled and regtested on
  aarch64-none-linux-gnu, aarch64_be-none-linux-gnu
  arm-none-eabi, armeb-none-eabi

and no issues.

Ok for master?

Thanks,
Tamar
