Log:
  Clean up OF_getprop_alloc API
  
  OF_getprop_alloc takes element size argument and returns number of
  elements in the property. There are valid use cases for such behavior
  but mostly API consumers pass 1 as element size to get string
  properties. What API users would expect from OF_getprop_alloc is to be
  a combination of malloc + OF_getprop with the same semantic of return
  value. This patch modifies API signature to match these expectations.
  
  For the valid use cases with element size != 1 and to reduce
  modification scope new OF_getprop_alloc_multi function has been
  introduced that behaves the same way OF_getprop_alloc behaved prior to
  this patch.
