[PATCH] can: flexcan: use of_property_read_u32 to avoid endian problem

Use of_property_read_u32() to get DT value can avoid endian problems,
this is needed since this driver can run on powerpc (be) and arm (le).

No need to check ret value here since we will check the got value to
verify if users pass a valid value in the DT.

This is the patch to replace the one "can: flexcan: use be32_to_cpup
to handle the value of dt entry", if you already applied that patch
and can't revert, please ignore this patch and let me know,i will
prepare an incremental patch basing on that one.
