security/vboot: Extend CROS_EC_HASH_TIMEOUT_MS

Browse source 
The ITE EC may take more than 2 seconds to complete EC FW
hash calculation in some corner cases. For example, boot with
a dead battery, EC even takes more than 10 seconds to complte
the hash calculation. Extend the timeout from 2 seconds to 12
seconds to cover the ITE EC cases, it should not impact boot
time and functionalities.
