Subject: [PATCH net v2] net: txgbe: fix i2c dev name cannot match clkdev

txgbe clkdev shortened clk_name, so i2c_dev info_name
also need to shorten. Otherwise, i2c_dev cannot initialize
clock. And had "i2c_dw" string in a define.

Fixes: e30cef001da2 ("net: txgbe: fix clk_name exceed MAX_DEV_ID limits")
