ARM: dts: Configure and fix the McSPI pins for 4430sdp
The bootloader configures the pins, but has pull bits set without pull enable bits. While this is harmless, and won't do anything, it seems to cause confusion at least for me every time looking at the pin configuration. Fix it for DT based boot. Signed-off-by: Tony Lindgren <tony@atomide.com>
