tpm/tpm_tis_spi: Add support for spi phy
Spi protocol standardized by the TCG is now supported by most of TPM
vendors.
It supports SPI Bit Protocol as describe in the TCG PTP
specification (chapter 6.4.6 SPI Bit Protocol).
Irq mode is not supported.
This commit is based on the initial work by Peter Huewe.
