Update binding for mt7988 which has 3 gmac and a sram for dma
operations.
MT7988 has 4 FE IRQs (currently only 2 are used) and 4 IRQs for use
with RSS/LRO later.
Add interrupt-names to make them accessible by name.
Signed-off-by: Frank Wunderlich <frank-w@public-files.de>
---
v6:
- update irq(name) min count to 4
- move interrupt-names up and limiting for all socs below
- add sram-property and drop second reg entry
- drop minitems as there is only 1 item left now
v5:
- fix v4 logmessage and change description a bit describing how i get
the irq count.
- update binding for 8 irqs with different names (rx,tx => fe0..fe3)
including the 2 reserved irqs which can be used later
- change rx-ringX to pdmaX to be closer to hardware documentation
v4:
- increase max interrupts to 6 because of adding RSS/LRO interrupts (4)
and dropping 2 reserved irqs (0+3) around rx+tx
- dropped Robs RB due to this change
- allow interrupt names
- add interrupt-names without reserved IRQs on mt7988
this requires mtk driver patch:
https://patchwork.kernel.org/project/netdevbpf/patch/20250616080738.117993-2-linux@fw-web.de/
v2:

In preparation for MT7988 and RSS/LRO allow the interrupt-names
property. Also increase the maximum IRQ count to 8 (4 FE + 4 RSS),
but set boundaries for all compatibles same as irq count.
