Battery Patching

At the moment, we direct users to Rehabman's guides on battery patching. I would like to move away from it at some point as users get confused trying to adapt Clover properties to their system. Main things I'd like to implement down the line:

* [ ] DSDT Patching
* For the most part, Rehabman's guides are fine. EC renames are something to mention
* [ ] Hotpatch coversions
* [ ] Dual Battery SSDT
* May just redirect users to [VirtualSMC repo](https://github.com/acidanthera/VirtualSMC/pull/28)
* [ ] Cycle Count
* May just redirect users to [VirtualSMC repo](https://github.com/acidanthera/VirtualSMC/blob/master/Docs/Transition%20from%20zprood's%20cycle%20count%20hack.md)

Battery patching in general is not a top priority, so would greatly appreciate any outside contributions like PRs. Would likely go in the [ACPI Guide](https://dortania.github.io/Getting-Started-With-ACPI/) as to fit with the rest.
