Randall Spangler 078dfabb68 Remove unneeded includes of registers.h
The registers.h file should only be included by code in the chip/ and
board/ directories.  Code outside those directories should not access
chip-specific registers.

(This change doesn't completely fix that, because
common/extpower_usb.c uses STM32-specific regs, but we'll fix that in
a separate CL.)
