Convert the tpm_tis_i2c driver to use driver model and update boards which
use it.

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.

This function is misnamed since it only applies to a single driver. Merge
its fields into its parent.

The function methods in struct tpm_vendor_specific just call local functions.
Change the code to use a direct call.

The current Infineon I2C TPM driver is written in two parts, intended to
support use with other I2C devices. However we don't have any users and the
Atmel I2C TPM device does not use this file.
We should simplify this and remove the unused abstration. As a first step,
move the code into one file.
Also the name tpm_private.h suggests that the header file is generic to all
TPMs but it is not. Rename it indicate that it relates only to this driver
