arm64: dts: qcom: sc8280xp: Set status = "reserved" on PSHOLD

Browse Source 
On most devices, TZ seems to be blocking access to the PSHOLD reboot
register. This seems to be TZ, as even kicking the hypervisor doesn't
seem to make it writable.

Fixes: 865ff2e6f5 ("arm64: dts: qcom: sc8280xp: Add PS_HOLD restart")
