MIPS: Malta: Fixup reboot
Commit 10b6ea0959de ("MIPS: Malta: Use syscon-reboot driver to reboot") converted the Malta board to use the generic syscon-reboot driver to handle reboots, but incorrectly used the value 0x4d rather than 0x42 as the magic to write to the reboot register. I also incorrectly believed that syscon/regmap would default to native endianness, but this isn't the case. Force this by specifying with a native-endian property in the devicetree.
