tpm: Refactor TPM Kconfig dimensions
Break TPM related Kconfig into the following dimensions:
TPM transport support:
config CRB_TPM
config I2C_TPM
config SPI_TPM
config MEMORY_MAPPED_TPM (new)
TPM brand, not defining any of these is valid, and result in "generic" support:
config TPM_ATMEL (new)
config TPM_GOOGLE (new)
config TPM_GOOGLE_CR50 (new, implies TPM_GOOGLE)
config TPM_GOOGLE_TI50 (new to be used later, implies TPM_GOOGLE)
What protocol the TPM chip supports:
config MAINBOARD_HAS_TPM1
config MAINBOARD_HAS_TPM2
What the user chooses to compile (restricted by the above):
config NO_TPM
config TPM1
config TPM2
The following Kconfigs will be replaced as indicated:
config TPM_CR50 -> TPM_GOOGLE
config MAINBOARD_HAS_CRB_TPM -> CRB_TPM
config MAINBOARD_HAS_I2C_TPM_ATMEL -> I2C_TPM && TPM_ATMEL
config MAINBOARD_HAS_I2C_TPM_CR50 -> I2C_TPM && TPM_GOOGLE
config MAINBOARD_HAS_I2C_TPM_GENERIC -> I2C_TPM && !TPM_GOOGLE && !TPM_ATMEL
config MAINBOARD_HAS_LPC_TPM -> MEMORY_MAPPED_TPM
config MAINBOARD_HAS_SPI_TPM -> SPI_TPM && !TPM_GOOGLE && !TPM_ATMEL
config MAINBOARD_HAS_SPI_TPM_CR50 -> SPI_TPM && TPM_GOOGLE
