The convention to name not connected GPIOs with NC has never been
adapted. Also newer Raspberry Pi boards like RPi 4 never did. So fix
this inconsistency by removing all of the NC names.

The GPIOs 46 & 47 are already used for a I2C interface to a SMPS.
So fix the GPIO line names accordingly.

There might be headless setups of the Compute Module without HDMI,
so better enable HDMI at board level. Btw this allows moving HDMI
base definition into upcoming bcm2835-common.dtsi.

Starting with RPi 4 this is the first board, which doesn't use sdhost
as default SD interface. So the MMC interfaces should be defined finally at
board level. Since all boards using sdhci already does this, we can drop the
pinctrl part from bcm2835-rpi.dtsi.

The Raspberry Pi Compute Module 3 (CM3) and the Raspberry Pi
Compute Module 3 Lite (CM3L) are SoMs which contains a BCM2837 processor,
1 GB RAM and a GPIO expander. The CM3 has a 4 GB eMMC, but on the CM3L
the eMMC is unpopulated and it's up to the user to connect their
own SD/MMC device. The dtsi file is designed to work for both modules.
There is also a matching carrier board which is called
Compute Module IO Board V3.
