For DA1469x if PM config is selected PM_DEVICE must also
be selected for GPIO to work when device enters/exists
deep sleep.
Previously GPIO and regulator drivers selected PM_DEVICE
when PM was enabled.
Now it is moved to SOC instead.
PM_DEVICE selection in GPIO could result in circular dependency
for mcux if MEMC_MCUX_FLEXSPI (which is already dependent on PM_DEVICE)
was to be additionally dependent on GPIO.

Removes conditional calling k_busy_wait() on single threaded
systems and uses k_sleep for both single and multi threaded

Commit e375d82 ("kernel: Implement k_sleep for Single Thread")
eliminated the need to call k_busy_wait() on single threaded
systems in place of k_sleep.

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.
