[PATCH 1/3] platform/x86: uniwill-laptop: Add PCSpecialist Recoil 16 AMD

[Mohamed Jouini <amad3v@gmail.com>]

The PCSpecialist Recoil 16 AMD is a rebadged TUXEDO Stellaris 16 Gen7 AMD
but reports sys_vendor "PCSpecialist" and board name "X6FR57TY", so the
existing entry does not match it.

Use the Stellaris 16 Gen7 AMD feature set, but with the percentage charge
limit instead of the charging profiles: on this firmware the "balanced"
profile does not limit charging (the battery still charges to full),
whereas the ACPI _BST method reads EC_ADDR_CHARGE_CTRL (CGLM) and reports
the "charge limiting" state bit while it is set to 1-99. Setting
charge_control_end_threshold to 90 on a full battery switches the
reported status from "Full" to "Not charging", and charging stops at 90%.
