I have gone through the data sheet as well as the manual, but didn't
find any timing related to hold time, setup time and max freq for SPI
interface.

A lot of this is handled by the settings of CPHA and CPOL - see
section 12.4.1 of the User Manual and the timing diagrams in section
12.2.2.

The Datasheet doesn't give any specific timing information.  So, send
a continuous stream of bytes and check it with a scope.

getting generated and how can I control the frequency of the SPI clock.

See section 12.4.4 of the User Manual
