Introduce MT8188-based Chromebook Ciri, also known commercially as
Lenovo Chromebook Duet (11", 9).

Ciri is a detachable device based on the Geralt design, where Geralt is
the codename for the MT8188 platform. Ciri offers 8 SKUs to accommodate
different combinations of second-source components, including:
- audio codecs (RT5682S and ES8326)
- speaker amps (TAS2563 and MAX98390)
- MIPI-DSI panels (BOE nv110wum-l60 and IVO t109nw41)

Changes in v3:
- drop scp_mem, scp_pins and SCP declaration per discussion in v2
- drop unused (for now) dual-SCP reserved memory range
- drop unused touchscreen pinctrl
- drop unused HID-I2C touchscreen node in I2C-2
- drop unused AP-SAR sensor node in I2C-3
- drop trackpad node in I2C-4 (only work with downstream CBAS)
- drop mmc1 (unused in public product)
- drop eDP panel path (unused in public product)
- declare DSI panel compatibles in individual board .dts files
- declare CPU TDP target in -geralt.dtsi instead
- move spi1 default and sleep pinctrl to -geralt.dtsi
- leave memory@40000000 size empty (filled by bootloader)
- consolidate audio codec/amplifier, DAI link declaration and
  audio-routing property
- stop sourcing `arm/cros-ec-sbs.dtsi` in -geralt.dtsi, because all that
  does is to declare sbs-battery at address 0xb, which doesn't align
  with the final design at 0xf. This saves us a /delete-node/.
- minor format fix

Changes in v2:
- remove invalid or undocumented properties
    e.g. mediatek,dai-link, maxim,dsm_param_name etc.
- remove touchscreen as the driver is not yet accepted in upstream
- update sound DAI link node name to match the binding
- add missing pinctrls in audio codec nodes
