Fixes OS-issues#217 and design#24

The datasheet says that it can take up to 1 second for conversion to be
finished, so there's no point in waiting for longer.

Also, disable HVDCP and MaxCharge to not negotiate high voltages
behind TPS65982's back.

Although the bit is called STAT_DIS (STAT Pin Disable), we're setting it
to 0, making the comment a bit confusing.

The charger is disabled anyway, and once it gets re-enabled
the value is already overwritten.

We don't use them.

read_vbat does additional stuff like disabling the charger and enabling
BAT_LOADEN to get more accurate reading, so use it to read the VBAT value.

According to the datasheet, the conversion is not finished until CONV_START
gets cleared, which can take up to 1 second (8.2.8 Battery Monitor).

Not sure what was the intention behind the old code, it doesn't look right.

The next line is supposed to restore register 0x03 to the old value, which
has no chance to work if we had just stored its current value into reg03.

debian: Bump firmware to 8.12

See merge request Librem5/uboot-imx!42

Enable WiFi SW kill switch

See merge request !40

Due to probe ordering in the kernel the SW kill switch might not get enabled
before the wifi driver is probed.

arm-trusted-firmware#1

This bumps the DP firmware version to 50d385ab:

    [   65.342684] cdns-mhdp-imx 32c00000.hdmi: [drm:cdns_mhdp_read_fw_version [cdns_mhdp_drmcore]] firmware version: 50d385ab

imx8mq_pins: fix configuration for UART4 on ECSPI2 pads

See merge request Librem5/uboot-imx!38

Move the board rev to the MAC address fuses

See merge request Librem5/uboot-imx!37

When routing UART4 using the ECSPI2 pads, register
IOMUXC_UART4_RXD_SELECT_INPUT (offset 0x050C) should be changed only
when dealing with RX, as its name suggests.

NXP has changed the layout of the OTP fuses and the user area is no longer
writable so we'll overload the MAC address as a board revision number.
