Found via static analyis. When `adc_kb1200_start_read` succeeds, no
value is set for `error` so it is still uninitialized when it is
returned.

k_thread_name_set() function returns an error if CONFIG_THREAD_NAME is
not enabled which may make the driver not functional.
Fix the issue by adding a check against CONFIG_THREAD_NAME avaliability
before calling k_thread_name_set() function so the driver can operate
properly with CONFIG_THREAD_NAME disabled.

Also fix the way the DMA channel is configured by using a standard DT

The TLA2021 driver depends on it's i2c controller and therefore needs
to be initialized later. ADC_INIT_PRIORITY by default equals
KERNEL_INIT_PRIORITY_DEVICE which should be used by independent devices.

enabled implicitly through board configuration and the priority is not
explicitly set.

Several STM32 variants include both shared IRQs for some ADCs and
separate IRQs for others (for example, STM32G473 has 5 ADCs, ADC1 and
ADC2 share one IRQ while ADC3, ADC4 and ADC5 each have unique
IRQs). The STM32 ADC driver however previously only supported either
separate IRQ lines for each operational ADC in the devicetree or a
single shared IRQ for all operational ADCs in the devicetree which
prevented all ADCs from being usable at the same time when the variant
contained a mix of both shared and separate ADC IRQ lines (only either
all the shared or all the separate and one of the shared might be used
at most for one application).
To allow for all ADCs in an STM32 variant to be usable in a single
application, generate an ISR and initialization function for each
unique IRQn as defined in the devicetree and give the task of
initialization to the first ADC which connects to that particular
IRQ. Each ISR function will generate code to call the ISR for each ADC
associated with that IRQn as was previously done for
CONFIG_ADC_STM32_SHARED_IRQS, allowing an ISR to be shared for the
ADCs sharing an IRQ while simultaneously providing separate ISRs for
each IRQ. Thus, the only information required to have ADCs either
share an ISR or not is provided by the devicetree.

When using one of the internal channels (die_temp, vbat, vref) the
channels are enabled in the individual drivers and disabled again
whenever an adc conversion is complete.
This creates a race condition if the ADC is used from multiple threads.
This commit moves the disabling of the channels to the individual
drivers.

Do not enable subsystem/driver shell modules by default and stop abusing
CONFIG_SHELL_MINIMAL, which is internal to the shell subsystem, to decide
when to enable a driver shell.
The list of shell modules has grown considerably through the
years. Enabling CONFIG_SHELL for doing e.g. an interactive debug session
leads to a large number of shell modules also being enabled unless
explicitly disabled, which again leads to non-negligible increases in
RAM/ROM usage.
This commit attempts to establish a policy of subsystem/driver shell
modules being disabled by default, requiring the user/application to
explicitly enable only those needed.
