ARM: tegra: Wire up two front panel LEDs on TrimSlice

Browse Source 
Pins responsible for controlling these LEDs need to have tristate
control removed if we want them as GPIOs. This change aligns with
pinmux configuration of "dte" pin group in downstream kernel[1].
These LEDs had no function assigned on vendor kernel and there is no
label on the case, the only markings are on PCB which are part of node
names (ds1 marking is on power LED controlled by PMIC), so generic term
is assigned as the function.
