2. Pull AC, then reattach AC
3. Verify "found battery in disconnect state" is seen on the
EC console.
4. Pull AC and verify that EC console is still accessable
Also verify that battery gets out of reset state:
1. Pull AC
2. Issue "i2cxfer w16 0 0x16 0x0 0x12" command on EC console
3. Re-attach AC
4. Pull AC and verify that EC console is still accessable

Only one EC was an i2c slave, samus_pd.
Now we have 2 more, ryu and ryu_sh (sensor hub).
Define a new variable: CONFIG_HOSTCMD_I2C_SLAVE_ADDR

This is a straightforward conversion of existing tables
into X-Macro style definitions for the GPIO alternate
functions. This change in itself, is not particularly
powerful, but having all GPIO settings in a single file
makes a board easier to understand.

Previously the F0 and L variants had almost identical driver files
and the F variant shared about half of its driver. This refactor
moves the shared code into gpio.c and gpio-f0-l.c, the latter
is for code shared between the F0 and L variants.
