system_is_locked: Use static variable to track state
When CONFIG_SYSTEM_UNLOCKED is not defined the function to
check if flash is write protected (flash_get_protect()) can
take up to 7ms to execute, and this function is called up to
18 times when booting from RO.
Use a static variable to track the status so we do not spend
so long executing this one function.
Without this change I would regularly see a PD hard reset when
booting without a battery and the system would fail to boot.
BUG=b:63957122
BRANCH=eve
TEST=manual testing to reliably boot without a battery on Eve
