I understand the reason behind using a perl script to parse some
text file in order to generate register's definition files,
but I can't see what's the sense of storing the perl script and
such texts together with the Kernel building system, re-generating them
every time.

I mean: register definitions is something that it is supposed to be
stable, and nothing something that will change on every Kernel
compilation.

How often are you expecting changes at ccs-regs.txt?
