Ender-3 default TMC currents #20

This PR reduces the current for TMC drivers since this config was using stock Marlin values.

Note: Stock motors are rated from the manufacturer using peak values instead of RMS (See https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3-/issues/22#issuecomment-525808256 and this gist from @knoopx), which is why these values are less than the advertised ratings of 840mA for X/Y/Z and 1000mA for E.
