    arm64: Add support for read and write registers at current EL in assembly
    
    In order to ease the process of reading and writing any register at current EL,
    provide read_current and write_current assembly macros. These are included in
    arch/lib_helpers.h under the __ASSEMBLY__ macro condition. This is done to allow
    the same header file to be included by .c and .S files.
