LLS: when turning off all LEDs on boot, skip LED-C
Having LLS turn off LED-A and LED-B on boot is normally unnecessary
(they should already be off in Iota), but it is harmless, hence this
logic is kept for robustness. However, having LLS read-modify-write
the BCICTL2 register (to turn off LED-C) creates a potential race
condition with FCHG writes to this register, especially in the case
when baseband switch-on is caused by VCHG and charging is expected
to start right away. Furthermore, control of the charging LED itself
(on those hw targets that have it) is the responsibility of the FCHG
SWE, hence LLS should leave it alone.
