ARM: tegra: add enable/disable/ramp time for rails

Add enable, disable ramp time for Jetson-E P2595 based
on system eng characterization. This is based on work
done in following changes for Loki/Foster

commit 349edb699efe4f9fb61533fb4271fb48a0d0ae64
ARM: tegra: Provide the enable/disable time for gpio controlled load switches

commit fde192d172f9b23123cbaab0c07c4c86c89352a6
ARM: tegra: provide the enable/disable/ramptime for Loki/Foster
