Clean up USB external power module
Make internal APIs static, and remove board_ prefix for clarity.
Move TSU6721 calls from charger task to extpower_usb functions for
better encapsulation.
No functional changes, just moving code. Yes, this will make
cherry-picking back from spring to TOT less convenient, but now the
code is more readable and it will make maintaining the PMU code easier
as we add boards.
