mb/lenovo/t60: Fix override devicetrees
Commit c1dc2d5e68
(mb/lenovo/t60: Switch to override tree) converted
these boards to override trees, but some device nodes were missed.
Said nodes are essential, as `chip` configuration data is always tied
to device nodes. The resulting `static.c` contained multiple copies
of the `chip` configuration structs, but the wrong ones were hooked up.
The therefore missing configuration of the clockgen led to general
instability, especially with SMP under Linux (probably due to the
attempt to enter lower C states on an idle core). Passing `maxcpus=1`
to the Linux kernel served as a workaround.
