Linker script rework
`memory.ld` is a architecture-dependent ld config provides some general
symbols which every `memory.ld` config must assign
and memory regions associated with each output section.
'linker.ld' config file presents segments configuration.
Multiboot section filling move in the 'linker.ld' file.
Recommendation for further patches: controlled logic implementation for multiboot
version and header/entries in build configuration tool (CMake or
make). For instance, multiboot version and video mode selection
through variable passing in build system:
`cmake ... -DMULTIBOOT_VERSION=2 -DMULTIBOOT_VIDEO_MODE=TEXT_VIDEO_MODE`
or
'export MULTIBOOT_VERSION=2; export MULTIBOOT_VIDEO_MODE=TEXT_VIDEO_MODE'.
Then build system do proper filling of `.multiboot` section depends
on passing variables.
