MLK-17142 arm64: dts: 8qxp: introduce dom0 dts

Introudce dom0 dts.
disable rtc, we do not have sip handler in xen, also need to modify the
driver to use hvc call.
remove gpu ss reg property to avoid overriding dom0 mapping.
Modify lpuart0 interrupt-parent to use gic, because xen could only
handle gic.
