AT91 PIO4 controller is a combined gpio-controller, pin-mux and
pin-config module. The peripheral's pins are assigned through
per-pin based muxing logic.
The pin configuration is performed on specific registers which
are shared along with the gpio controller. So regard the pinctrl
device as a child of atmel_pio4 device.

Commit 302c5db ("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.
Commit 3e7d940 ("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 code may want to read reg values from DT, but from nodes that aren't
associated with DM devices, so using dev_get_addr_index() isn't
appropriate. In this case, fdtdec_get_addr_size_*() are the functions to
use. However, "translation" (via the chain of ranges properties in parent
nodes) may still be desirable. Add a function parameter to request that,
and implement it. Update all call sites to default to the original

Commit 4b50369fb5 ("ARM: uniphier: create early page table at

run-time page table creation requires the outer cache register
access but the page table in the sLD3 Boot ROM does not straight-map
virtual/physical addresses.
The idea here is to check the current page table to determine if
it is a straight map table. If not, adjust the outer cache register
base.
