Kconfig: provide MAINBOARD_HAS_TPM_CR50 option

The CR50 TPM can do both SPI and I2C communication. However,
there's situations where policy needs to be applied for CR50
generically regardless of the I/O transport. Therefore add
MAINBOARD_HAS_TPM_CR50 to encompass that.  Additionally,
once the mainboard has selected CR50 TPM automatically select
MAINBOARD_HAS_TPM2 since CR50 TPM is TPM 2.0.
