Subject: [PATCH v2 4/7] ACPI: thermal: Move acpi_thermal_driver definition

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Move the definition of the acpi_thermal_driver structure closer to the
initialization code that registes the driver, so some function forward
declarations can be dropped.

Also move the module information to the end of the file where it is
usually located.

No functional impact.

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
---

v1 -> v2: Rearranged the code so as to put the suspend/resume callback
  definitions into one #define block (instead of two).
