Subject: [PATCH 26/84] arm64: dts: mediatek: mt7988: add basic ethernet-nodes
Add basic ethernet related nodes.
Mac1+2 needs pcs (sgmii+usxgmii) to work correctly which will be linked
later when driver is merged.

v8:
- change ethernet register size to 0x40000
range from 0x15140000 ~ 0x1517ffff is not usable on mt7988 => 0xDEADBEEF
v6:
- fix whitespace-errors for pdma irqs (spaces vs. tabs)
- move sram from eth reg to own sram node (needs CONFIG_SRAM)
v5:
- add reserved irqs and change names to fe0..fe3
- change rx-ringX to pdmaX to be closer to documentation
v4:
- comment for fixed-link on gmac0
- update 2g5 phy node
- unit-name dec instead of hex to match reg property
- move compatible before reg
- drop phy-mode
- add interrupts for RSS
- add interrupt-names and drop reserved irqs for ethernet
- some reordering
- eth-reg and clock whitespace-fix based on angelos review
