[PATCH] ufs: ufshcd: Use of_property_count_u32_elems() to get property length

["Rob Herring (Arm)" <robh@kernel.org>]

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.
