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>
