arm: tegra: hawkeye: keep mipi_1v2 on in shutdown

Currently mipi_1v2 gets disabled by the MAX77620 driver
during shut down. This happens before the DSI driver
gets a chance to properly disable the panel.

Removing the regulator-disable-on-shutdown flag for
the mipi_1v2 and its LDO leaves power on for the DSI
driver. The rail is shut down later in the shut down
sequence.

Bug 1656676
