The ethernet controller of SG2044 is Synopsys DesignWare IP with
custom clock. Add glue layer for it.

Since v2, these patch depends on that following patch that provides
helper function to compute rgmii clock:
https://lore.kernel.org/netdev/20241013-upstream_s32cc_gmac-v3-4-d84b5a67b930@oss.nxp.com/

Changed from v1:
1. patch 2: remove sophgo,syscon as this mac delay is resolved.
2. patch 2: apply all the properties unconditionally.
3. patch 4: remove sophgo,syscon code as this mac delay is resolved.
4. patch 4: use the helper function to compute rgmii clock.
5. patch 4: use remove instead of remove_new for the platform driver.
