Wei Fang Oct. 22, 2024, 5:52 a.m. UTC
Compile enetc_pf_common.c as a standalone module to allow shared usage
between ENETC v1 and v4 PF drivers. Add struct enetc_pf_ops to register
different hardware operation interfaces for both ENETC v1 and v4 PF
drivers.

Signed-off-by: Wei Fang <wei.fang@nxp.com>

v2 changes:
This patch is separated from v1 patch 5 ("net: enetc: add enetc-pf-common
driver support"), only the changes to compile enetc_pf_common.c into a
separated driver are kept.
v3 changes:
Refactor the commit message.
v4 changes: Remove the input prompt of CONFIG_NXP_ENETC_PF_COMMON.
