Subject: [PATCH v16 2/4] ARM: power-domain: rockchip: add all the domain type on RK3288 SoCs

According to a description from TRM, the following table lists
all the power domains.

------------------------   -------------------------
|VD_CORE               |   |VD_LOGIC    |  PD_VIO  |
|xxxxxxxxxxxxxxxxxxxx  |   |xxxxxxxx    -----------|
|xxxxxxxxxxxxxxxxxxxx  |   |xxxxxxxx               |
|xxxxxxxxxxxxxxxxxxxx  |   |                       |
|xxxxxxxxxxxxxxxxxxxx  |   |---------   -----------|
|                      |   |PD_PERI  |  | PD_VIDEO |
|                      |   |---------   -----------|
|                      |   |---------   -----------|
|                      |   |PD_ALIVE |  | PD_HEVC  |
|---------- ---------- |   |---------   -----------|
||PD_A17_1| |PD_A17_2| |   -------------------------
|---------- ---------- |   |VD_GPU      |PD_GPU    |
|---------- ---------- |   -------------------------
||PD_A17_3| |PD_DEBUG| |   -------------------------
|---------- ---------- |   |VD_PMU      |PD_PMU    |
------------------------   -------------------------
VD_* :  voltage domain
PD_* :  power domain

At the moment, we can support some power-domain type on RK3288.
We can add more types on RK3288 in the future, that's need to do.
