Why I did it (#14826)

Midstone platform has compilation error in master branch, fixed the same.

How I did it
Due to bullseye migration i2c_new_dummy API is deprecated modified with i2c_new_dummy_device.

How to verify it
Verified target/debs/bullseye/platform-modules-midstone-200i_0.2.2_amd64.deb is generated
