This patch set adds hardware temperature and power reading support for
APM X-Gene SoC using the mailbox communication interface.
For device tree, it is the standard DT mailbox.
For ACPI, it is the PCC mailbox.
For ACPI, tested with this patch[1] which supports PCC subspace 2

- [PATCH v3] mailbox: pcc: Support HW-Reduced Communication Subspace type 2
v2
- Increase power reading accurateness by using 2 registers
(a register for Watt, another for milli-Watt)
- Remove power reading for SoC
- Fix review comments from Guenter
v1
- Initial
