Previously usb_charger.c supported only pi3usb9281, but now support for
additional parts is required. Move pericom-specific code (including the
usb_charger tasks that handles various quirks of that part) to the
pi3usb9281 usb_switch driver.
Going forward, usb_switch drivers must implement
usb_charger_set_switches() and must have some method (such as a task or
interrupt handler) to update charge_manager with information about
attached chargers.

This unifies all the EC header files to use __CROS_EC_FILENAME_H
as the include guard. Well, except for test/ util/ and extra/
which use __TEST_ __UTIL_ and __EXTRA_ prefixes respectively.

Previously we supported using a single pi3usb9281 chip, or using two
chips on the same i2c bus behind a mux. Now that we need to support a
third configuration of multiple chips on different busses, it makes
sense to be able to configure the configuration freely at the board
level.

Bits 1 and 3 of the control register are read 1, write 1, but RO
firmware may have zero'd these bits. Therefore, always set the bits
high, ignoring the read value.
TEST=Manual on Samus. Starting from .90 RO, flash new RW and verify
BC1.2 charger detection is working.

REG_CONTROL has two sets of reserved bits:
- Bits 5 thru 7 are read x, write 0.
- Bits 1 and 3 have undocumented function and should not be changed from
read value.

Samus USB ports can't actually act as UFPs, so open switches when in
UFP mode.
BUG=chrome-os-partner:32003
TEST=Manual on Samus. Connect two Samus units, run `pd 1 swap data`,
verify that switches are opened on switch to UFP. Unplug samus and
connect a USB 2.0 device instead, verify that ports are again closed.

Also adds new charging suppliers for pericom identified chargers
including DCP, CDP, SDP, proprietary, and other chargers. Priority
of these for charging is set in samus board file.
