Subject: [PATCH v2] arm64: dts: qcom: x1e80100: Disable the SMB2360 4th
 instance by default

The CRD board doesn't have the 4th SMB2360 PMIC populated while the QCP
does. So enable it on QCP only. This fixes the warning for the missing
PMIC on CRD as well.

Fixes: 2559e61e7ef4 ("arm64: dts: qcom: x1e80100-pmics: Add the missing PMICs")
