charger: support the charger without battery
In order to support the HW design with charger but doesn't include
the a battery, we exclude the charge_state_v2.c if we define the
CONFIG_CHARGER but not define the CONFIG_BATTERY. Besides, we also
implement some default functions to avoid the link error.
Note: remove the charge_prevent_power_on from the board.c of
rainier/mchpevb1 and use the default function.
BUG=b:242949656
BRANCH=none
TEST=build pass with
1. CONFIG_CHARGER + CONFIG_BATTERY
2. CONFIG_CHARGER + no CONFIG_BATTERY
3. make buildall
