kexec_file, arm64: print out debugging message if required
Then when specifying '-d' for kexec_file_load interface, loaded locations
of kernel/initrd/cmdline etc can be printed out to help debug.
Here replace pr_debug() with the newly added kexec_dprintk() in kexec_file
loading related codes.
And also remove the kimage->segment[] printing because the generic code
has done the printing.
