arm64: dts: qcom: sm8450: Add Xperia 5 IV support

Add a device tree for the Xperia 5 IV (pdx224). It's literally the 1 IV
with a smaller body, different panel, one camera lens (not sensor afaict)
swapped out and no 3D iToF sensor, hence the device-specific DT is tiny.

Be sure to follow the vbmeta disablement steps (detailed in pdx223
introduction commit message), otherwise your phone will not boot and
will reject anything and everything with just a non-descriptive
"Your device is corrupted" followed by a sad reboot. This should not
be the case, as vbmeta should be plainly ignored in unlocked state,
but what can we do..
