Subject: [PATCH net v5] 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.

Change log:
v4-v5: address comments:
	Jiri Pirko:
	Well, since it is used in txgbe_phy.c, it should be probably
	rather defined locally in txgbe_phy.c.
v3->v4: address comments:
	Jakub Kicinski:
	No empty lines between Fixes and Signed-off... please.
v2->v3: address comments:
	Jiawen Wu:
	Please add the define in txgbe_type.h

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