Fix regprop int encoding (Igor Kovalenko)

Browse Source 
Wrong encoding of "#address-cells" property can lead to a failure
fetching correct value in my-#acells method. According to docs
properties must be encoded with "encode-int". I spent some time
looking at the docs and it is clear that encode-int produces
quad-sized result (of size /l bytes).

This patch fixes pci helpers to encode to 32bit instead of 64bit values,
and correctes my-address and my-unit methods to read 32bit data
to match encode-int rules
modules/bindings.c: also fixed set_int_property and get_int_property
to match encode-int rules
