The devm_pinctrl_register() function returns an error pointer or a valid
handle. So checking for NULL here is pointless and can never trigger.
Check the returned value with IS_ERR instead and propagate this value as
done in the other functions which call devm_pinctrl_register().

When we split a large object up into chunks for GTT faulting (because we
can't fit the whole object into the aperture) we have to align our cuts
with the fence registers. Each partial VMA must cover a complete set of
tile rows or the offset into each partial VMA is not aligned with the
whole image. Currently we enforce a minimum size on each partial VMA,
but this minimum size itself was not aligned to the tile row causing
distortion.

This reverts commit 36b30d6138.
This is necessary to detect paz00 (ac100) touchpad properly as one
speaking ETPS/2 protocol. Without it X.org's synaptics driver doesn't
work as the touchpad is detected as an ImPS/2 mouse instead.
Commit ec6184b1c7 changed the way
auto-detection is performed on ports marked as pass through and made the
issue apparent.
A pass through port is an additional PS/2 port used to connect a slave
device to a master device that is using PS/2 to communicate with the
host (so slave's PS/2 communication is tunneled over master's PS/2
link). "Synaptics PS/2 TouchPad Interfacing Guide" describes such a
setup (PS/2 PASS-THROUGH OPTION section).
Since paz00's embedded controller is not connected to a PS/2 port
itself, the PS/2 interface it exposes is not a pass-through one.

The Kconfig currently controlling compilation of this code is:
arch/cris/arch-v10/drivers/Kconfig:config ETRAX_SERIAL
arch/cris/arch-v10/drivers/Kconfig: bool "Serial-port support"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.
We don't replace module.h with init.h since the file already has that.

`ni_tio_clock_period_ps()` used to return the clock period in
picoseconds, and had a `BUG()` call for invalid cases. It was changed
to pass the clock period back via a pointer parameter and return an
error for the invalid cases. Unfortunately the code to handle
user-specified clock sources with user-specified clock period is still
returning the clock period the old way, which can lead to the caller not
getting the clock period, or seeing an unexpected error. Fix it by
passing the clock period via the pointer parameter and returning `0`.
