JIRA: https://issues.redhat.com/browse/RHEL-101059

commit 14f1585
Author: Anshuman Khandual <anshuman.khandual@arm.com>
Date: Sun, 21 Sep 2025 06:22:58 +0530

    Update TCR_EL1 register fields as per latest ARM ARM DDI 0487 L.B and while
    here drop an explicit sysreg definition SYS_TCR_EL1 from sysreg.h, which is
    now redundant.
