[PATCH v4 2/6] arm64: tegra: Add device-tree node for NVVRS PSEQ

[Shubhi Garg <shgarg@nvidia.com>]

Add NVIDIA VRS Power Sequencer device tree node for Tegra234 P3701 and
P3767 platforms. Assign VRS RTC as primary RTC (rtc0).

Signed-off-by: Shubhi Garg <shgarg@nvidia.com>

v4:
- fixed device tree node name to "pmic@3c" in aliases

v3:
- fixed device tree node name to generic "pmic@3c"

v2:
- added alias to assign VRS RTC to rtc0
- removed status node from VRS DTB node
