platform/x86: thinkpad_acpi: fix kernel-doc warnings

  Add a function's return description and don't misuse "/**" for
non-kernel-doc comments to prevent warnings from scripts/kernel-doc.

thinkpad_acpi.c:523: warning: No description found for return value of 'tpacpi_check_quirks'
thinkpad_acpi.c:9307: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
thinkpad_acpi.c:9307: warning: missing initial short description on line:
 * This evaluates a ACPI method call specific to the battery

Thank you for your contribution, it has been applied to my local
review-ilpo branch. Note it will show up in the public
platform-drivers-x86/review-ilpo branch only once I've pushed my
local branch there, which might take a while.
