alpha: beautify vmlinux.lds

Introduced a consistent style in vmlinux.lds and it now matches the
soon-to-be common style for all arch's vmlinux.lds files.

In addition:
- Replaced hardcoded constant with PAGE_SIZE
- Fix page.h so PAGE_SIZE can be used from assembler and in lds files
- Move a few labels inside brackets so linker alignment will not
  make label point ot a too low address
- Replaced DWARF and STABS sections with definitions from asm-generic
