Add a new display-inversion property to ili9xxx based display drivers to
send a "Display Inversion ON (0x21)" command during initialization.
This seems to be required for some ILI9xxx based displays to work
correctly, such as BuyDisplay ER-TFT028A2-4 (ILI9341 basd IPS display).

Convert driver(s) to DEVICE_DEFINE instead of DEVICE_AND_API_INIT
so we can deprecate DEVICE_AND_API_INIT in the future.

- Remove SYS_ prefix
- shorten POWER_MANAGEMENT to just PM
- DEVICE_POWER_MANAGEMENT -> PM_DEVICE
and use PM_ as the prefix for all PM related Kconfigs

Use the core k_heap API pervasively within our tree instead of the
z_mem_pool wrapper that provided compatibility with the older mempool
implementation.
Almost all of this is straightforward swapping of one alloc/free call
for another. In a few cases where code was holding onto an old-style
"mem_block" a local compatibility struct with a single field has been
swapped in to keep the invasiveness of the changes down.
Note that not all the relevant changes in this patch have in-tree test
coverage, though I validated that it all builds.

Make driver generic for multiple ILI displays. The adopted strategy is
to share all driver code except register initialization, which has been
found to have some specific registers/values depending on the
controller.
The driver has been adjusted to support multiple compatibles.

For drivers that support CONFIG_DEVICE_POWER_MANAGEMENT there are some
cases that look like:
#ifdef CONFIG_DEVICE_POWER_MANAGEMENT
DEVICE_DEFINE()
#else
DEVICE_AND_API_INIT()
#endif
There is no need to special case this as the pm_control_fn argument to
DEVICE_DEFINE will just be ignored in the
!CONFIG_DEVICE_POWER_MANAGEMENT case. So we can cleanup the code a
little and remove the #else cases for the drivers that do this.

Align register names with the ones found in the datasheet. It is easier
to follow datasheet if names are the same.
Some other minor enhancements have also been introduced (comments, use
BIT for bit fields...).

The driver-specific config_info structure referenced from the device
structure is marked const. Some drivers fail to preserve that
qualifier when casting the pointer to the driver-specific structure,
violating MISRA 11.8.
Changes produced by scripts/coccinelle/const_config_info.cocci.
Some changes proposed by the script are not included because they
reveal mutation of state through the const pointer, though the
code works as long as the driver-specific object is defined without
the const qualifier.
