mb/google/brya: Init TPM in bootblock when not using vboot
Brya queries the TPM in early ramstage (pre-device init) to determine if the CR50 has support for long-pulse interrupts. If the TPM (and underlying I2C controller) hasn't already been setup in verstage, it will fail to do so in ramstage since the I2C controller has not yet been initialized. To work around this, initialize the TPM in bootblock for the non-vboot case, to ensure the I2C controller is set up when needed in early ramstage. TEST=build/boot google/brya (banshee), verify no I2C errors in cbmem console when initializing TPM in early ramstage.
