net: txgbe: fix clk_name exceed MAX_DEV_ID limits 

txgbe register clk which name is i2c_designware.pci_dev_id(),
clk_name will be stored in clk_lookup_alloc. If PCIe bus number
is larger than 0x39, clk_name size will be larger than 20 bytes.
It exceeds clk_lookup_alloc MAX_DEV_ID limits. So the driver
shortened clk_name.
