mb/hp: select TPM and TPM1 for all EliteBook laptops

All the Sandy/Ivy Bridge EliteBook and ProBook laptops currently
supported by coreboot and on review all support TPM 1.2 according the
maintenance and service guide manuals of these laptops. So select the
Kconfig options of TPM and TPM 1.2 and add the entry of it to the
common device tree.

The device tree C source files of 8460p generated by sconfig before
and after this change are compared. All the device nodes still exist
with nodes under LPC having different device number.

Tested with 2560p, which still works without problems, and the TPM can
be detected and used in the system.
