    arm/mem_access: Introduce BIT_ULL bit operation
    
    We introduce the BIT_ULL macro to using values of unsigned long long as
    to enable setting bits of 64-bit registers on AArch32.  In addition,
    this commit adds a define holding the register width of 64 bit
    double-word registers. This define simplifies using the associated
    constants in the following commits.
