Since both CONFIG_ACPI and CONFIG_CLKSRC_OF can be enabled on ARM64, we get this device tree warnings even when booting using ACPI which is not valid. We can use of_have_populated_dt to check if the device tree is populated or not and avoid spurious warning.
This patch uses of_have_populated_dt to remove this non legitimate device tree warning when booting using ACPI tables.
