The property for enabling external rail control on the AS3722 is
ams,ext-control, not ams,external-control. Since the external rail
control property was previously being ignored, LP1 suspend on these
boards wasn't actually turning the CPU rail off at all.

Jetson TK1 contains an RT5639 not an RT5640. While the two are extremely
similar and mostly compatible, we should still use the correct device
name in the device tree. I had meant to fix this before applying the
initial DT, but this issue slipped my mind.

Add HDMI +5V, VDD and PLL regulators and enable the DDC I2C controller.
Enable the HDMI device, provide the power supplies as well as the DDC
adapter and use pin the standard pin (PN7) for hotplug detection.

Regulator vddio_sdmmc3 provides the Tegra<->SD IO voltage, not the card
core supply voltage. That is, it provides vqmmc, not vmmc. Fix the DT to
correctly reflect this.

These are mostly identical to the Venice2 regulator definitions, since
the board designs are very similar. Differences are:
- Jetson TK1 doesn't have a built-in LCD panel, so on-board regulators
are not present for the backlight, touchscreen, or panel.
- +3.3V_RUN needs to be boot-on/always-on, since it's widely used. This
change should likely be propagated to Venice2 for completeness,
although it will have no practical effect there since various other
regulators use +3.3V_RUN as their supply and are always-on.
- +3.3V_LP0 needs to be boot-on as well as always-on. One reason
is because it's used to driver the UART level-shifter; without this, I
see a brief period of UART corruption during cold boots.I suspect this
change needs to be propagated to Venice2, and we simply haven't noticed
the need since there's no UART level-shifter on Venice2.
- A few rails have different names in the schematics.

Jetson TK1 is an NVIDIA Tegra124 development board, containing Tegra124,
2GB RAM, eMMC, SD card, SPI flash, serial port, PCIe Ethernet, HDMI,
audio, mini PCIe, JTAG, SATA, and an expansion IO connector containing
GPIOs, I2C, SPI, CSI, eDP, etc.
The following features work with this device tree: UART, SD card, eMMC,
SPI flash, USB (full-size jack, and mini-PCIe), audio, AS3722 RTC, system
power-off, suspend/resume (LP1) with wake via RTC alarm.
The following features should work with this device tree, but are not
validated: Expansion I2C, expansion SPI, expansion GPIO, gpio-key for the
power button.
The following features are not yet implemented in this device tree: Most
voltage regulators, expansion UART, HDMI, eDP, PCIe (Ethernet, and mini-
PCIe connector), CSI, SATA.
