fix(bootloader): fixed image cannot exceed 16MB issue

Browse Source 
flash 32-bit-addr is an experimental feature that has multiple
dependencies, e.g. flash chip vendor, etc.

If CONFIG_BOOTLOADER_CACHE_32BIT_ADDR_QUAD_FLASH can be enabled
successfully and tests are passed, we can allow images to be
placed on higher-than-16MB flash addresses
