Use tcl script instead of static xmls for the interface.
Easier to maintain and are not gitignored.
Rename spi_master to spi_engine because every interface should be
prefixed by the IP name; in this case, spi_engine.
Also, remove interface/*.sv files on make clean and git ignore them.

The coraz7s has an Arduino/chipKIT Shield connector with 6 Single-ended
and 8 Differential Analog inputs tied to Xilinx's XADC.
The CN0540 uses the A0-5 pins as single-ended ADC channels to monitor
the differential input, ADC driver, and buffer voltages.

Generate a higher frequency of spi_clk using an axi_clkgen. (MMCM)
CAUTION: ad7768-1 is still violating the standard SPI timing,
reducing the timing window significantly for the last bit (or last high
bit).
