- only power key can request irq thread;
- this makes key framework be able to manage all key interrupt event;

- use standard dm framework to implement all key drivers;
- all key node to be children and attach to key bus;
- dm key uclass takes over most work;
- reduce a lot of driver code size;

We add recovery key node with property "u-boot,dm-pre-reloc"
in uboot dts in order to make sure recovery key works normally
even when kernel dtb is load failed. But There are too many
boards for a platform(eg. RK3399/RK3399PRO), which may cause
a mistake key match between boards via U-Boot dts key nodes,
so that we make kernel dtb key has higher priority.

1. dm key framework takes over more generic jobs;
2. key drivers remove unused codes and match new framework;
3. only power key is registered as interrupt key;
