drivers/tpm: Move TPM init to end of device init phase
Boards which use an I2C TPM and do not use vboot will not have the I2C bus initialized/ready at the start of the device init phase. If TPM init is called before the bus, init will fail with I2C transfer timeouts and a significantly lengthened boot time. Resolves: https://ticket.coreboot.org/issues/429 TEST=build/boot google/reef w/o vboot, verify successful TPM init.
