Add AiO HotPlug (complete sysFS entries and Descriptions are provided)

[Shoaib0597]

Hi @yoinx,

I request you to add AiO HotPlug, an All in One HotPlug for Traditional Quad-Core and Hexa/Octa-Core big.LITTLE SoCs. I have developed this HotPlug myself.

This HotPlug offers a total of 4 sysFS entries. They are (order-wise)---

1. Enable/Disable Toggle---
sysFS Path---
/sys/kernel/AiO_HotPlug/toggle
Range---
1 or 0

2. A Traditional "Number of Online Cores" SeekBar---
sysFS Path---
/sys/kernel/AiO_HotPlug/cores
Range---
1 to 4

3. A "big Cluster" SeekBar---
sysFS Path---
/sys/kernel/AiO_HotPlug/big_cores
Range---
0 to 2 (on Hexa-Core big.LITTLE SoCs)
0 to 4 (on Octa-Core big.LITTLE SoCs)
Note:
At value 0, the entire Cluster will be switched off.

4. A "LITTLE Cluster" SeekBar---
sysFS Path---
/sys/kernel/AiO_HotPlug/LITTLE_cores
Range---
0 to 4
Note:
At value 0, the entire Cluster will be switched off.

Misc. Notes--

1. The HotPlug will expose only 1 and 2 sysFS entries if it is running on a Traditional Quad-Core SoC.
2. The HotPlug will expose only 1, 3 and 4 sysFS entries if it is running on a Hexa/Octa-Core big.LITTLE SoC.

Optional Requests---
1. Titles and Descriptions---
a. Enable/Disable Toggle---
Main Title-----AiO HotPlug
Description---An All in One HotPlug, developed by Shoaib Anwar a.k.a. Shoaib0597, for all main types of SoCs.

b. "Number of Online Cores" SeekBar
Main Title-----Number of Online Cores
Description---No Description (Leave Blank)

c. "big Cluster" SeekBar---
Main Title-----big Cluster
Description---Set the Number of Online Cores. At value 0, the entire Cluster will be switched off (only if atleast 1 LITTLE Core is active and HotPlug Boost Toggle (available in CPU TAB) is Enabled).
Note: At value of 0 of this SeekBar, instead of showing "0", show "Offline".

d. "LITTLE Cluster" SeekBar---
Main Title-----LITTLE Cluster
Description---Set the Number of Online Cores. At value 0, the entire Cluster will be switched off (only if atleast 1 big Core is active).
Note: At value of 0 of this SeekBar, instead of showing "0", show "Offline".

2. Please, if possible, try to copy/paste these descriptions exactly. :)

Thanks! I hope this gets merged soon. :)
