[PATCH v2 0/2] usb: typec: ucsi: acpi: Zero version quirk for Lenovo ThinkPad T14 Gen 2a

[Stanisław Titenko via B4 Relay]

The ThinkPad T14 Gen 2a firmware leaves the UCSI VERSION field at zero,
so ucsi_acpi does not register the Type-C ports. Mark Pearson is asking
Lenovo's firmware team to look at it; this quirk is the fallback in case
a firmware fix is not possible.

Patch 1 renames the existing Acer quirk to a neutral name, patch 2 uses
it for the ThinkPad T14 Gen 2a.

Changes in v2:
- Reuse the Acer zero version quirk instead of a new Lenovo copy, so the
  assumed version is now 1.2 instead of 1.0 (Mark Pearson).
- Match on DMI_BOARD_NAME 20XK and 20XL instead of the product version
  string (Mark Pearson).
- Link to v1: https://patch.msgid.link/20261031-ucsi-lenovo-t14g2a-v1-1-183751e63c02@xxxxxxxxxx
