Allwinner A31 has introduced a new memory mapping and a reset line. The difference in memory mapping are : - In the configure register there is a new sample bit and Allwinner has introduced the active threshold feature. - In the status register a new STAT bit is present. Note: CGPO and DRQ_EN bits are removed on A31 but present on A13 and on new SoCs like A64/H6. This is actually not an issue as these bits are togglable and new SoCs have a dedicated bindings. Introduce this bindings to make a difference since this generation. And declare the reset line required since A31.
