[PATCH 0/2] arm64: dts: agilex5: add support for debug daughter card

[Adrian Ng Ho Yin <adrian.ho.yin.ng@altera.com>]

The Agilex5 SoCDK supports an optional debug daughter card that requires
a dedicated device tree variant due to differences in peripheral
connectivity compared to the standard SoCDK configuration.

When the debug daughter card is fitted:
  - gpio0 and gmac2 are disabled
  - gmac0 is enabled with RGMII PHY connectivity
  - spi0 is enabled with a <device> peripheral at chip select 0
  - The HPS LED is rewired from gpio0/porta to gpio1/portb

The new DTS inherits from socfpga_agilex5_socdk.dts and overrides only
the nodes that differ, keeping the delta minimal.
