Revert "Fix MSIM Network Settings (1/2)"

A public intent shouldn't need additional parameters to trigger.

This reverts commit 6cf32469f14a2c0efad9da34a5f12a9d341fc762.

Settings: correct y-axis brightness in preview

To answer the comment in the code, no, the min brightness should not
correspond 0, but rather to the device min supported level. The values
on the preview graph should correspond exactly to the percent values
entered in the brightness configuration dialog.
