arch: arm: dts: agilex5: Set spi-max-freq to 50Mhz

Browse Source 
This patch is to set spi-max-freq to 50Mhz. This will add support to the
driver to set the operation speed according to the slave device up to
50Mhz. Without this node, the driver just can adjust the operation speed
to the default speed which is far below the best
operation speed of the SPI slave device.
