pata_octeon_cf: use of_property_read_{bool|u32}()
The Octeon CF driver basically open-codes of_property_read_{bool|u32}() using of_{find|get}_property() calls in its probe() method. Using the modern DT APIs saves 2 LoCs and 16 bytes of object code (MIPS gcc 3.4.3). Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: Tejun Heo <tj@kernel.org>
