Roland Stigge c076ada4e4 i2c: pnx: Fix read transactions of >= 2 bytes 
On transactions with n>=2 bytes, the controller actually wrongly clocks in n+1
bytes. This is caused by the (wrong) assumption that RFE in the Status Register
is 1 iff there is no byte already ordered (via a dummy TX byte). This lead to
the implementation of synchronized byte ordering, e.g.:

Dummy-TX - RX - Dummy-TX - RX - ...

But since RFE actually stays high after some Dummy-TX, it rather looks like:

Dummy-TX - Dummy-TX - RX - Dummy-TX - RX - (RX)

The last RX byte is clocked in by the bus controller, but ignored by the kernel
when filling the userspace buffer.

This patch fixes the issue by asking for RX via Dummy-TX asynchronously.
Introducing a separate counter for TX bytes.
