CIRCT & Chisel bumping needs to be re-enable

[Avimitin]

The latest Chisel on master branch will breaks our arithmetic module with following error:

> [error]            ^
> [error] /build/source/dependencies/arithmetic/arithmetic/src/division/srt/srt4/SRT4.scala:9:8: object leftShift is not a member of package chisel3.utils
> [error] import utils.leftShift

> [error]       ^

But currently we have no plan to rewrite the arithmetic module, so that the Chisel bump action will never success. Before we migrate to DWBB, the CIRCT & Chisel bumping action is disabled.

To re-enable action, goes to the action page and scroll down to Chisel and CIRCT bumping page, click the "Enable workflow" button.
