[PATCH] xilinx: versal-net: fix no previous prototype for function warning.

[Prasad Kummari]

Included the SPI header to resolve the no previous prototypes
for function. Removed unused mode variable.
sparse warnings
warning: no previous prototype for 'spi_get_env_dev'
[-Wmissing-prototypes]
warning: variable 'mode' set but not used
[-Wunused-but-set-variable]
