spi_flash: RAM loadable ELF should have dangerous writes option allowed

For RAM loadable ELF case, there is no application or the bootloader on
the flash. And hence the check for getting current running OTA partition
or looking up partition table fails during dangerous writes option.

We are disabling the dangerous writes option for RAM loadable ELF case
and allowing writes to entire flash memory.
