The driver originally supported more domains (register ranges) per
pinctrl device, but since commit 9dab1868ec ("pinctrl: amlogic: Make
driver independent from two-domain configuration") each device gets
assigned a single domain and we instantiate multiple pinctrl devices
in the DT.
Therefore, now the 'meson_domain' and 'meson_domain_data' structures
don't have any reason to exist and can be removed to make the model
simpler to understand. This commit doesn't change behavior.
Tested on a Odroid-C2.

In the Amlogic Meson8 / Meson8b platforms we have two different buses:
cbus and aobus, corresponding to 2 different power domains (regular and
always-on). On each bus a different set of registers is mapped to manage
muxes, GPIOs and in general to control a clear subset of the pins.
Considering this architecture, having two different pinctrl devices, one
for each bus / power domain, makes much more sense than just having one
single device.
Right now we have one single pin controller driver that uses two
different domains (represented by 'gpio' and 'gpio-ao' sub-nodes in the
DTS) to manage the set of registers on the two buses. This dual-domain
configuration is hardcoded into the driver that strictly requires one
domain for each bus in the same pin controller device.
With this patch we refactor the driver to allow splitting the driver in
two parts. This change is needed to have a proper description of the HW
in the device-tree where we want to introduce aobus and cbus.

The num_pins field in the struct meson_domain_data must include also the
missing pins in the Meson8b SoC, otherwise the GPIO <-> pin mapping is
broken on this platform. Avoid also the dinamic allocation for GPIOs.
