soc: espressif: esp32s2: simple boot support
Add simplistic booting method which allows to run applications without the 2nd stage bootloader. - introduce memory layout header file - update and optimize default and mcuboot linker scripts - remove building multiple binaries during the application build Signed-off-by: Marek Matej <marek.matej@espressif.com>
