For zynqmp qspi, frequencies up to 40MHz will work irrespective
of feedback clock enabled or disabled. If we want higher than
40Mhz the feedback clock should be enabled.
With spi-max-frequency 108MHz it is not working when the feedback
clock is disabled. Change it to 40MHz so that it works irrespective
of feedback clock enabled or disabled.

Add configuration files/dtses for mini u-boot configuration
which runs on smaller footprint of internal memory. This
configuration has only required qspi flash support and it
uses DCC as serial.
