kexec: define functions to map and unmap segments
Implement kimage_map_segment() to enable IMA to map the measurement log
list to the kimage structure during the kexec 'load' stage. This function
gathers the source pages within the specified address range, and maps them
to a contiguous virtual address range.
This is a preparation for later usage.
Implement kimage_unmap_segment() for unmapping segments using vunmap().
