dm: add amp uclass and rockchip amp driver support

- add amp uclass;
- add a simple rockchip amp driver.

An example for amps dts node configure:
amps {
compatible = "uboot,rockchip-amp";
status = "okay";

amp@0 {
description = "mcu-os1";
partition = "mcu1";
cpu = <0x1>; // this is mpidr!
load = <0x800000>;
entry = <0x800000>;
memory = <0x800000 0x400000>;
};

amp@1 {
......
};

......
};

U-Boot loads "mcu-os1" firmware to "0x800000" address from partiton
"mcu1" for cpu[1], the cpu[1] entry address is 0x800000. And
U-Boot reserve memory from 0x800000 with 0x400000 size in order
to make it invisible for kernel.

Please use rockchip tool "mkkrnlimg" to pack firmware binary, example:
./scripts/mkkrnlimg mcu-os1.bin mcu-os1.img

dm: Implement a CPU uclass

It is useful to be able to keep track of the available CPUs in a multi-CPU
system. This uclass is mostly intended for use with SMP systems.

The uclass provides methods for getting basic information about each CPU.
