Can this be handled by feature flag instead of listing soc/series in driver?

What is funny, the last option NRF_SOC_SECURE_SUPPORTED
is handled exactly opposite:

	def_bool !TRUSTED_EXECUTION_NONSECURE || (BUILD_WITH_TFM && TFM_PARTITION_PLATFORM)
	depends on !SOC_SERIES_NRF54H
	depends on !SOC_SERIES_NRF92
	help
	  Hidden function to indicate that the soc_secure functions are
	  available.
	  The functions are always available when not in non-secure.
	  For non-secure the functions must redirect to secure services exposed
	  by the secure firmware.

select HWINFO_HAS_DRIVER
help
Enable Nordic NRF hwinfo driver.
