tpm: Reorganize the I2C TPM driver
This patch does a similar code reogranzation from http://patchwork.ozlabs.org/patch/132179/ which is based on an old version of code (fdt support and bus selection still not in). It merges this tidy-up on top of the recent code. It does not make any logical change. tpm.c implements the interface defined in tpm.h based on underlying LPC or I2C TPM driver. tpm.c and the underlying driver communicate throught tpm_private.h. Note: Merging the LPC driver with tpm.c is left to future patches.
