[PATCH v2 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 is unrouted and remains disabled
  - gmac2 is replaced by gmac0 for Ethernet connectivity
  - spi0 is connected to a Microchip 25AA128 16 KByte SPI EEPROM

changelog:
v1->v2:
- Use socfpga_agilex5.dtsi as the base include instead of
  socfpga_agilex5_socdk.dts to follow the convention that .dts files
  are final compilation units and should not be included by other files
- Replace spidev node (with fake rohm,dh2228fv compatible) with a
  proper atmel,at25 EEPROM binding describing the actual hardware
- Remove dmas/dma-names from spi0: CONFIG_DW_AXI_DMAC is not enabled
  in the platform defconfig and retaining them stalls the SPI driver
  in probe deferral
- Remove incorrect HPS LED GPIO override; the LED mapping is unchanged
  from the base board
