Subject: [PATCH 6/7] arm64: dts: exynos: Mark arch_timer device as
 not-fw-configured on TM2(e)

TM2(e) boards use old firmware, which some PCSI requirements and doesn't
properly configure arch virtual timers, so add property indicating this
state. This enables respective workarounds in the timer driver.
