commit 59c17fae900de697e44f7c22c5cceb6af3c1e66a
Author:     Andrew Turner <andrew at FreeBSD.org>

    Update the SCTLR_EL1 register definitions
    
    They are valid as of the ARMv8.7 XML.
    
    While here remove SCTLR_RES0 as it's unused and depends on which CPU
    the kernel is running on and switch to shifted values as they are
    easier to compare with the documentation.
