Jarkko Nikula 30930f0f46 i2c: designware: Fix RX FIFO depth define on Wangxun 10Gb NIC
[ Upstream commit c94612a72ac87b0337a0d85b9263266776ed4190 ]

I believe RX FIFO depth define 0 is incorrect on Wangxun 10Gb NIC. It
must be at least 1 since code is able to read received data from the
DW_IC_DATA_CMD register.

For now this define is irrelevant since the txgbe_i2c_dw_xfer_quirk()
doesn't use the rx_fifo_depth member variable of struct dw_i2c_dev but
is needed when converting code into generic polling mode implementation.
