The current LB_BOOT_MODE_LOW_BATTERY actually implies a state where the
battery is below the critical threshold but a charger is attached,
allowing the system to boot into a charging-only or limited state.
Update the enum name to LB_BOOT_MODE_LOW_BATTERY_CHARGING across
coreboot tables and libpayload to better reflect this hardware state.
Changes:
- Rename boot mode enums in commonlib and libpayload.
- Update bluey mainboard logic to use the more descriptive name.
- Refactor is_low_power_boot() to is_low_power_boot_with_charger()
to improve code readability.
- Ensure the charger-present condition is explicitly checked in
romstage when setting the boot mode.
TEST=Verify bluey boots into off-mode charging and low-battery
charging modes correctly.
