dt-bindings: power: reset: qcom-pon: Only allow reboot-mode pre-pmk8350
As pointed out by Shazad [1], PMICs using a separate HLOS+PBS scheme
(so PMK8350 and newer) are expected to pass reboot mode data through SDAM,
as the reboot mode registers are absent in the HLOS reg space.
Limit the reboot-mode.yaml inclusion to PMICs without a separate PBS
region.
