The extentions were added to make the compiler perform most
of the verification that the conversion was being done correctly
to remove 8bit addressing as the standard I2C/SPI address type.
Now that the compiler has verified the code, the extra
extentions are being removed

Opt for 7bit slave addresses in EC code. If 8bit is
expected by a driver, make it local and show this in
the naming.
Use __7b, __7bf and __8b as name extensions for i2c/spi
addresses used in the EC codebase. __7b indicates a
7bit address by itself. __7bf indicates a 7bit address
with optional flags attached. __8b indicates a 8bit
address by itself.
Allow space for 10bit addresses, even though this is
not currently being used by any of our attached
devices.
These extensions are for verification purposes only and
will be removed in the last pass of this ticket. I want
to make sure the variable names reflect the type to help
eliminate future 7/8/7-flags confusion.

Intel SoC needs which USB2/3 ports are assigned to which Type-C ports.
This patch adds USB2 and USB3 port numbers to tcpc_config_t so that
EC_CMD_LOCATE_CHIP can return it to the host.

Currently, tcpc_config assumes TCPCs are on I2C bus. ITE's EC has an
embedded TCPC.
This patch adds bus_type field to struct tcpc_config_t so that a TCPC
location on other type of bus can be specified.

This patch replaces EC_CMD_I2C_LOOKUP with EC_CMD_LOCATE_CHIP.
This is a more generic command which locates a peripheral chip in
i2c or other bus types.
Additionally, it includes the following changes:
- Change chip (device) type # of CBI_EEPROM (from 1 to 0).
- Support TCPCs.
localhost ~ # ectool locatechip 0 0
BUS: I2C; Port: 0; Address: 0x50 (7-bit format)
localhost ~ # ectool locatechip 1 0
BUS: I2C; Port: 0; Address: 0x0b (7-bit format)
localhost ~ # ectool locatechip 1 1
BUS: I2C; Port: 1; Address: 0x29 (7-bit format)
localhost ~ # ectool locatechip 1 2
EC result 11 (OVERFLOW)
Index too large
localhost ~ # ectool locatechip 2
Usage: locatechip <type> <index>
<type> is one of:
0: CBI_EEPROM
1: TCPCs
<index> instance # of <type>
