Currently we have a single dsa_switch_ops for 4 very distinct families of switches, and many dsa_switch_ops methods are simply a dispatches through ksz_dev_ops. That creates an avoidable level of indirection. As a preparation for removing that indirection layer, create a separate dsa_switch_ops structure wherever we have a ksz_dev_ops. These structures are not yet used - ksz_switch_ops from ksz_common.c still is. However, this reduces the noise from subsequent changes. All new dsa_switch_ops are exact copies of ksz_switch_ops. But we need to export function prototypes from ksz_common.c so that they are callable from individual drivers. Note that "individual drivers" are not actual separate kernel modules. All of ksz8.c, ksz9477.c and lan937x_main.c are part of the same ksz_switch.ko. Only the "register interface" drivers are different modules (ksz9477_i2c.o for I2C, ksz_spi.o for SPI, ksz8863_smi.o for MDIO). So we don't need to export any symbol.
