platform/x86: thinkpad_acpi: Handle KCOV __init vs inline mismatches 

When KCOV is enabled all functions get instrumented, unless the
__no_sanitize_coverage attribute is used. To prepare for
__no_sanitize_coverage being applied to __init functions[1], we have
to handle differences in how GCC's inline optimizations get resolved.
For thinkpad_acpi routines, this means forcing two functions to be
inline with __always_inline.
