Change subject: mb/google/volteer: Skip TPM detection except on SPI
......................................................................

Patch Set 7:

All the actual Volteer variants will have CONFIG(MAINBOARD_HAS_SPI_TPM_CR50) enabled, and in that case, it is obvious to see that this CL is a no-op.

Only the reworked Volteer prototypes, hooked up with external Dauntless development board, will use I2C instead of SPI for TPM communication, and could be affected by the logic change here.

Furquan, could you please +2 this.
