scsi: ufs: ufshcd-pltfrm: Use of_property_count_u32_elems() to get property length

Browse Source 
Replace of_get_property() with the type specific
of_property_count_u32_elems() to get the property length.

This is part of a larger effort to remove callers of of_get_property() and
similar functions. of_get_property() leaks the DT property data pointer
which is a problem for dynamically allocated nodes which may be freed.
