mb/google/volteer: ACPI nodes for volteer2_ti50
Unique among the Volteer devices, the volteer2_ti50 variant connects to
the TPM via I2C. This CL introduces the proper devicestree declarations
for the Linux kernel to recognize that.
overridetree.cb is shared between "sub"-variants volteer2 and
volteer2_ti50, so both will have two TPM nodes, the I2C being disabled
by default. The odd _ti50 variant then has code in variant.c to enable
the I2C node and disable the SPI node.
BUG=b:173461736
TEST=abuild -t GOOGLE_VOLTEER2{_TI50,} -c max -x
