include/linux/property.h: fix build issues with gcc-4.4.4

gcc-4.4.4 has problems with initialization of anonymous unions:

drivers/mfd/intel-lpss-acpi.c:30: error: unknown field 'value' specified in initializer

work around this by crafting the initializers in a manner which the
compiler can handle.
