This is first time that the NETC IP is applied on i.MX MPU platform.
Its revision has been upgraded to 4.1, which is very different from
the NETC of LS1028A (its revision is 1.0). Therefore, some existing
drivers of NETC devices in the Linux kernel are not compatible with
the current hardware. For example, the fsl-enetc driver is used to
drive the ENETC PF of LS1028A, but for i.MX95 ENETC PF, its registers
and tables configuration are very different from those of LS1028A,
and only the station interface (SI) part remains basically the same.
For the SI part, Vladimir has separated the fsl-enetc-core driver, so
we can reuse this driver on i.MX95. However, for other parts of PF,
the fsl-enetc driver cannot be reused, so the nxp-enetc4 driver is
added to support revision 4.1 and later.

During the development process, we found that the two PF drivers have
some interfaces with basically the same logic, and the only difference
is the hardware configuration. So in order to reuse these interfaces
and reduce code redundancy, we extracted these interfaces and compiled
them into a separate nxp-enetc-pf-common driver for use by the two PF
drivers.

In addition, we have developed the nxp-netc-blk-ctrl driver, which
is used to control three blocks, namely Integrated Endpoint Register
Block (IERB), Privileged Register Block (PRB) and NETCMIX block. The
IERB contains registers that are used for pre-boot initialization,
debug, and non-customer configuration. The PRB controls global reset
and global error handling for NETC. The NETCMIX block is mainly used
to set MII protocol and PCS protocol of the links, it also contains
settings for some other functions.
