x86: place application data before kernel data

Kernel data size shifts in between linker passes due to the addition
of the page tables. We would like application memory bounds to
remain fixed so that we can program the MMU permissions for it
at build time.

/**
 * @file
 * @brief Common linker sections
 *
 * This script defines the memory location of the various sections that make up
 * a Zephyr Kernel image. This file is used by the linker.
 *
 * This script places the various sections of the image according to what
 * features are enabled by the kernel's configuration options.
 *
 * For a build that does not use the execute in place (XIP) feature, the script
 * generates an image suitable for loading into and executing from RAMABLE_REGION by
 * placing all the sections adjacent to each other.  There is also no separate
 * load address for the DATA section which means it doesn't have to be copied
 * into RAMABLE_REGION.
 *
 * For builds using XIP, there is a different load memory address (LMA) and
 * virtual memory address (VMA) for the DATA section.  In this case the DATA
 * section is copied into RAMABLE_REGION at runtime.
 *
 * When building an XIP image the data section is placed into ROMABLE_REGION.  In this
 * case, the LMA is set to __data_rom_start so the data section is concatenated
 * at the end of the RODATA section.  At runtime, the DATA section is copied
 * into the RAMABLE_REGION region so it can be accessed with read and write permission.
 *
 * Most symbols defined in the sections below are subject to be referenced in
 * the Zephyr Kernel image. If a symbol is used but not defined the linker will
 * emit an undefined symbol error.
 *
 * Please do not change the order of the section as the kernel expects this
 * order when programming the MMU.

linker: nios2: align rodata section

linker: nios2: align rodata section

During testing with sorting section by alignment with qemu_nios2,
if rodata section is not aligned on 4-byte boundary and its size
not of multiple of 4, it would never boot correctly. So align
the rodata here. This is in preparation to enable the linker
option to sort sections by alignment.
