ARM: sun6i: Add restart code for the A31 The Allwinner A31 has a different watchdog, with a slightly different register layout, that requires a different restart code. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

- compatible : should be "allwinner,<soc-family>-wdt", the currently supported
SoC families being sun4i and sun6i

- reg : Specifies base physical address and size of the registers.

ARM: sunxi: Rework the restart code The Allwinner sun6i (A31) has a slightly different watchdog, that doesn't allow to use the already existing restart code. Rework a bit the restart code to allow to plug in more easily different restart handlers depending on the device tree. In the past, we were also meaning sunxi as a generic name covering all Allwinner SoCs. This won't be true anymore with the A31 (sun6i) that differs pretty much from sun4i and sun5i, and we will end up having sunxi, for sun4i and sun5i, and sun6i, which is neither consistent nor convenient. So, while we're at it, also change sunxi to sun4i. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
