hw/arm/virt: Remove the dtb-kaslr-seed machine option

Eric Auger requested to merge eauger1/centos-qemu-kvm:kaslr-seed into c9s

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2046029 Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=45133161 Upstream Status: RHEL-only Tested: Boot RHEL guest and check the option is not available

In RHEL we do not want to expose the dtb-kaslr-seed virt machine option. Indeed the default 'on' value matches our need as random data in the DTB does not cause any boot failure and we want to support KASLR for the guest.

While at it, fix an oversight related to highmem_mmio and highmem_redists init in rhel_virt_instance_init()

Updated the brew TaskID now the issue with the brew build has been fixed.
