[PARISC] Beautify parisc vmlinux.lds.S
Introduce a consistent layout of vmlinux. The same layout has been introduced for most architectures. And the same time move a few label definitions inside the curly brackets so they are assigned the correct starting address. Before a ld inserted alignment would have casued the label to pint before the actual start of the section.
