soc: keystone_serdes: create a separate SGMII SerDes driver
This patch split the Keystone II SGMII SerDes related code from
Ethernet driver and create a separate SGMII SerDes driver.
The SerDes driver can be used by others keystone subsystems
like PCI, sRIO, so move it to driver/soc/keystone directory.
Add soc specific drivers directory like in the Linux kernel.
It is going to be used by keysotone soc specific drivers.
