common: Fix sleep mask for multi-port lock.stabilize-smaug-7897.B
This change use a simple counter to to prevent ec enter sleep if there's
any i2c port active. Once there's no i2c port active, we enable sleep bit of
i2c in i2c_lock() func. Please note FW disables interrupt during changing
counter to prevent preemptive conditions.
