[PATCH RFC 4/6] The common header ksz_priv.h does not contain chip specific data

[PATCH RFC 4/6] The common header ksz_priv.h does not contain chip specific data

[Tristram.Ha]

From: Tristram Ha <Tristram.Ha@microchip.com>

The header ksz_priv.h is used by all KSZ switch drivers so chip specific data are removed and commonly used variables are added.
