Add a new sysreset driver based on linux/drivers/power/reset/syscon-reboot.c, which provides a generic driver for platforms that only require writing a mask to a regmap offset.

Signed-off-by: Álvaro Fernández Rojas noltari@gmail.com Reviewed-by: Simon Glass sjg@chromium.org --- v4: Rebased. v3: Introduce changes suggested by Simon Glass: - Add missing driver description. - Alphabetically order includes. - Add priv struct to store regmap during probe. - Cosmetic fixes. v2: No changes.
