fastchg: Only enable fast charge GPIO as long as we actually have some charging to do.
Enable fast charge by default.
Revert "Manually set LINUX_COMPILE_BY and LINUX_COMPILE_HOST"

This reverts commit a17af8c5988eb7427b7bff4d672686c51ec72eef.

While I think I understand the reasoning for this, I think the
original purpose for these should be used instead (to identify
who actually built the kernel).
Add FML config based on FancyKernel-Big config.

Switches default I/O scheduler to ROW, among other things.
