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.
