platform/x86: thinkpad_acpi: Fix profile mode display in AMT mode

Browse Source 
Recently AMT mode was enabled (somewhat unexpectedly) on the Lenovo
Z13 platform. The FW is advertising it is available and the driver tries
to use it - unfortunately it reports the profile mode incorrectly.

Note, there is also some extra work needed to enable the dynamic aspect
of AMT support that I will be following up with; but more testing is
needed first. This patch just fixes things so the profiles are reported
correctly.
