platform/mellanox: fix potential deadlock in the tmfifo driver

This commit fixes the potential deadlock caused by the console Rx
and Tx processing at the same time. Rx and Tx both take the console
and tmfifo spinlock but in different order which causes potential
deadlock. The fix is to use different tmfifo spinlock for Rx and
Tx since they protect different resources and it's safe to split
the lock.

Below is the reported call trace when copying/pasting large string
in the console.

Intel PMC and accompanying drivers are cleaned up.

- Mellanox got a new TmFifo driver. Besides tachometer sensor and
watchdog are enabled on Mellanox platforms.

- The information of embedded controller is now recognized on new
Thinkpads. Bluetooth driver on Thinkpads is blacklisted for some
models.
