In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.
This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.
The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

Remove servo_v4p1 custom ioex implementations for TCA64xxA modules.
Enable I/O expander module and move from custom interface to
generic one.
Due to the lack of flash in RW section, IOEX is not available there and
required 'board_id_det' function is stubbed using raw i2c functions.
This results in IOEX and DAC functions available only in RO section,
so their initialization functions are moved to RO-only init.
BUG=b:168385201
BRANCH=main
TEST=Connect to servo's console and execute 'ioexget' command.
All IOEX pins' states should be printed in terminal.
Pin TCA_GPIO_DBG_LED_K_ODL should change as LED is blinking.
TEST=Connect to servo's console. Plug USB-C charger to servo power
port. 'ioexget' command should display EN_PP5000_ALT_3P3 value
as 1. Execute 'ioexset EN_PP5000_ALT_3P3 0' command.
Unplug fast the servo charger. Servo should be fully operational
without any sign of reboot.

Fix improper GPIO connections and add new ones in ioexpanders to match
EVT hardware layout. Old assignments were implemented for PVT design.

The flash is partitioned as follows:
96K for RO
40K for RW
The bulk of the code is placed in RO and RW
is used for software updates.
This initial checkin implements the following
functionality:
1) Software updates over servo_updater
