Liang Chen 4ee45c385f soc: rockchip: rockchip_performance: optimize tasks schedule policy 
When level==0(low-performance mode):
1. prefer prev_cpu for rt tasks if prev cpu is fit.
2. make sure that it saves at least 6% of the energy when
migrate tasks from little cpu to big cpu.

When level==2(high-performance mode):
1. do not use EAS path.
2. select big cpu first when system is not overutilized.
3. do not trigger load_balance() when system is not overutilized.
4. prefer prev_cpu for rt tasks if prev cpu is fit.

Test performance improvement for level==2:

1. CONFIG_ROCKCHIP_PERFORMANCE=n
EMMC Random Write(4KB) 25.44MB/s
Antutu:
Total 581266
CPU   133023
GPU   234106
MEM   103602
UX    110535

2. CONFIG_ROCKCHIP_PERFORMANCE=y and level==2
EMMC Random Write(4KB) 44.19MB/s (73.7% improvement)
Antutu:
Total 600483 (3.3% improvement)
CPU   134481 (1.1% improvement)
GPU   234678
MEM   116551 (12.5% improvement)
UX    114773 (3.8% improvement)
