Commit302c5db("dm: tpm: Add Driver Model support for tpm_atmel_twi driver") converted the Atmel TWI TPM driver itself to driver model, but kept the legacy-style i2c_write/i2c_read calls. Commit3e7d940("dm: tpm: Every TPM drivers should depends on DM_TPM") then made DM_I2C a dependency of the driver, effectively forcing users to turn on CONFIG_DM_I2C_COMPAT to get it to work. This patch adds the necessary dm_i2c_write/dm_i2c_read calls to make the driver compatible with DM, but also keeps the legacy calls in ifdefs, so that the driver is now compatible with both DM and non-DM setups.

Some broken TPMs have a limitation on the number of bytes they can

receive in one message. Enable this option to allow you to set this
