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.

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

Since commit 2580a2a7 ("mtd: nand: Increase max sizes of OOB and
Page size"), three boards (ph1_ld4, ph1_pro4, ph1_sld8) fail to build
with the following error message:
  arm-linux-gnueabi-ld.bfd: SPL image plus BSS too big

They compile drivers/mtd/nand/denali_spl.c and it has a page_buffer
as static data:

    static uint8_t page_buffer[NAND_MAX_PAGESIZE];

This buffer required 8KB in .bss section before that commit and now
it has been increased to 16KB.  Given limited code/memory size for SPL,
it is not a good idea to allocate a page buffer statically.  In the
first place, the load address 'dst' can be used as a page buffer.
