mtd: map_ram: prevent use of point and unpoint when NO_XIP is set
When the DT property no-unaligned-direct-access is set, map->phys is set to NO_XIP. With this property set, the flash should not be exposed directly to MTD users, since it cannot be mapped. map_ram() exposes the flash direct access unconditionally which leads to access errors (when the bus width does not match the RAM width). Therefore do not set point and unpoint when NO_XIP is set.
