[PATCH v5 1/2] of: Documentation: Specify local APIC ID in "reg"

[Ivan Gorinov]

Set the "reg" property to the processor's local APIC ID.
Local APIC ID is assigned by hardware and may differ from CPU number.

-The reg property describes the CPU number. The lapic property points to
-the local APIC timer.
+A "cpu" node describes one logical processor (hardware thread).
+
+Required properties:
+
+- device_type
+	Device type, must be "cpu".
+
+- reg
+	Local APIC ID, a unique number assigned to each processor by
+	hardware. This ID is used to specify the destination of interrupt
+	messages with "physical" destination mode, including startup IPI.
