ixgbe/base: rework semaphore

- Store lan_id and physical semaphore mask into hardware physical information,
and use them to control read and write physical registers in IXGBE base code.
- Extend mask from 16 bits to 32 bits for releasing or acquiring SWFW semaphore
in IXGBE base code. It is used in reading and writing I2C byte.
