[PATCH] acpi: respect const qualifier

[Semen Protsenko <semen.protsenko@linaro.org>]

This patch fixes next warning:

<------------------------------- cut here --------------------------------->
drivers/acpi/property.c: In function ‘acpi_free_properties’:
drivers/acpi/property.c:35:2: warning: passing argument 1 of ‘acpi_os_free’
                              discards ‘const’ qualifier from pointer
                              target type [enabled by default]

  ACPI_FREE(adev->properties);
<------------------------------- cut here --------------------------------->

The problem is next:

 - acpi_free_properties() calls ACPI_FREE(), passing "const *"
   parameter to it
 - ACPI_FREE() is macro for acpi_os_free()
 - acpi_os_free() takes "void *" parameter
 - acpi_os_free() calls kfree()
 - but kfree() requires "const void *" parameter

So acpi_os_free() should require "const void *" parameter as well.
