media: dt-bindings: media: sunxi-ir: Add A31 compatible
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.
