Add a new uclass for TPMs which uses almost the same TIS (TPM Interface
Specification) as is currently implemented. Since init() is handled by the
normal driver model probe() method, we don't need to implement that. Also
rename the transfer method to xfer() which is a less clumbsy name.

Once all drivers and users are converted to driver model we can remove the
old code.

Use a _US suffix for microseconds and a _MS suffic for milliseconds. Move
all timeouts and delays into one place. Use mdelay() instead of udelay()
where appropriate.

Some definitions are in the C file and some are in the header file. Move
everything into the header file for consistency and to reduce clutter.

There are too many structures storing the same sort of information. Move the
fields from struct tpm into struct tpm_chip and remove the former struct.
