[v3,0/5] Add Renesas RZ/V2M Ethernet support

Message

The RZ/V2M Ethernet is very similar to R-Car Gen3 Ethernet-AVB, though
some small parts are the same as R-Car Gen2.
Other differences are:
* It has separate data (DI), error (Line 1) and management (Line 2) irqs
  rather than one irq for all three.
* Instead of using the High-speed peripheral bus clock for gPTP, it has
  a separate gPTP reference clock.

v3:
 * Really renamed irq_en_dis_regs to irq_en_dis this time
 * Modified ravb_ptp_extts() to use irq_en_dis
 * Added Reviewed-by tags

v2:
 * Just net patches in this series
 * Instead of reusing ch22 and ch24 interrupt names, use the proper names
 * Renamed irq_en_dis_regs to irq_en_dis
 * Squashed use of GIC reg versus GIE/GID and got rid of separate gptp_ptm_gic feature.
 * Move err_mgmt_irqs code under multi_irqs
 * Minor editing of the commit msgs
