Eero Nurkkala 53b58b0881 risc-v/mpfs: i2c: fix an FPGA known issue
This fixes the following issue:
  - After sending the address, the driver writes an extra zero

Without this patch, the extra write causes an extra ACK that would
terminate the sequence prematurely. This is observed as data read
corruption.

With this fix, the condition is detected precisely. That being the
case, the sequence is continued with a repeated start, after which
the read continues normally.
