arm64: dts: socfpga: agilex: Add 4-bit SPI bus width
Add spi-tx-bus-width and spi-rx-bus-width properties with value 4 to the
agilex device tree. This update configures the SPI controller to use a
4-bit bus width for both transmission and reception, potentially improving
SPI throughput and matching the hardware capabilities more closely.
