This patch moves the ksz_chip_data in ksz8795 and ksz9477 to ksz_common.
At present, the dev->chip_id is iterated with the ksz_chip_data and then
copy its value to the ksz_dev structure. These values are declared as
constant.
Instead of copying the values and referencing it, this patch update the
dev->info to the ksz_chip_data based on the chip_id in the init
function. And also update the ksz_chip_data values for the LAN937x based
switches.
