MMCC is a component of the SoC that should always be configured. It was kept
off due to misconfiguration on clamshell machines. Keep it disabled on these
ones and enable it by default on all the others.

Exactly the same story applies to MMSS_SMMU, which directly depends on MMCC.

Do note, that if a platform doesn't use neither EFIFB (only applies to WoA
devices in this case) or simplefb (applies to precisely 2 msm8998 devices

sc7280-herobrine based boards are specced to be able to access their
SPI flash at 50 MHz with the drive strength of the pins set at 8. The
drive strength is already set to 8 in "sc7280-herobrine.dtsi", so
let's bump up the clock. The matching firmware change for this is at:

https://review.coreboot.org/c/coreboot/+/63948

NOTE: the firmware change isn't _required_ to make the kernel work at
50 MHz, it merely shows that the boards are known to work fine at 50
MHz.

ALSO NOTE: this doesn't update the "sc7280-chrome-common.dtsi" file
which is used by both herobrine boards and IDP. At the moment the IDP
boards aren't configuring a drive strength of 8 and it seems safer to
just leave them at the slower speed if they're already working.

This copy-pastes compatibles from sc7180-based boards from the device
trees to the yaml file so that `make dtbs_check` will be happy.

NOTES:
- I make no attempt to try to share an "item" for all sc7180 based
  Chromebooks. Because of the revision matching scheme used by the
  Chromebook bootloader, at times we need a different number of
  revisions listed.
- Some of the odd entries in here (like google,homestar-rev23 or the
  fact that "Google Lazor Limozeen without Touchscreen" changed from
  sku5 to sku6) are not typos but simply reflect reality.
- Many revisions of boards here never actually went to consumers, but
  they are still in use within various companies that were involved in
  Chromebook development. Since Chromebooks are developed with an
  "upstream first" methodology, having these revisions supported with
  upstream Linux is important. Making it easy for Chromebooks to be
  developed with an "upstream first" methodology is valuable to the
  upstream community because it improves the quality of upstream and
  gets Chromebooks supported with vanilla upstream faster.

One other note here is that, though the bootloader effectively treats
the list of compatibles in a given device tree as unordered, some
people would prefer future boards to list higher-numbered revisions
first in the list. Chromebooks here are not changing and typically
list lower revisions first just to avoid churn.

On herobrine boards the keyboard backlight is controlled through the
PWM LED driver. Currently both the PWM LED node and the node for the
keyboard backlight are disabled in sc7280-herobrine.dtsi, which
requires boards with a backlit keyboard to enable both nodes. There
are no other PWM LEDs on herobrine boards besides the keyboard
backlight, delete the 'disabled' status from the keyboard backlight
node, with that boards only have to enable the 'pwmleds' node for
keyboard backlight support.

This adds the touchscreen to the sc7280-herobrine-villager device
tree. Note that the touchscreen on villager actually uses the reset
line and thus we use the more specific "elan,ekth6915" compatible
which allows us to specify the reset.

The fact that villager's touchscreen uses the reset line can be
contrasted against the touchscreen for CRD/herobrine-r1. On those
boards, even though the touchscreen goes to the display, it's not
hooked up to anything there.

In order to keep the line parked on herobrine/CRD, we'll move the
pullup from the qcard.dtsi file to the specific boards. This allows us
to disable the pullup in the villager device tree since the pin is an
output.
