zephyr: Compilation fails when CONFIG_FLASH_PAGE_LAYOUT is disabled

[de-nordic]

The MCUboot support code provides the flash_area_get_sectors implementation in https://github.com/mcu-tools/mcuboot/blob/main/boot/zephyr/flash_map_legacy.c for devices that does not have support for "flash pages layout",
Devices that provide support for pages layout select CONFIG_FLASH_HAS_PAGE_LAYOUT that enables option CONFIG_FLASH_PAGE_LAYOUT; this option is selected (enforced) when available by the CONFIG_MCUBOOT_DEVICE_SETTINGS, so to test this a device that does not select CONFIG_FLASH_HAS_PAGE_LAYOUT needs to be selected or

mcuboot/boot/zephyr/Kconfig

Lines 612 to 621 in 46e554e

	config MCUBOOT_DEVICE_SETTINGS
	# Hidden selector for device-specific settings
	bool
	default y
	# CPU options
	select MCUBOOT_DEVICE_CPU_CORTEX_M0 if CPU_CORTEX_M0
	# Enable flash page layout if available
	select FLASH_PAGE_LAYOUT if FLASH_HAS_PAGE_LAYOUT
	# Enable flash_map module as flash I/O back-end
	select FLASH_MAP

has to be modified in line 613 to not select the option.
After such configuration is prepared, the below command executed from Zephyr root:

west build -d voot -b nrf52840dk_nrf52840 bootloader/mcuboot/boot/zephyr/ -DCONFIG_FLASH_PAGE_LAYOUT=n

causes following warnings and errors (and a lot more):
