Servo v4: reduce RO flash size
Currently, the servo_v4 build is within 48 bytes of exceeding its RO
flash size. With this change to remove the USART3 code from the RO
image, there should be just about 350 free bytes of space.
BRANCH=None
BUG=None
TEST=builds, hey_flash_used in RO elf file shows 0x170 free bytes
