hw/char/parallel: Make it possible to compile also without CONFIG_PARALLEL
For the downstream distribution of QEMU, we want to compile without CONFIG_PARALLEL. Commit 9157eee1b1c076ff3 already moved the function parallel_hds_isa_init() (which is still required for linking) into a file that is included anyway, but commit bb3d5ea858e7f888563a moved it to a separate file which is only compiled again if CONFIG_PARALLEL is set. To be able to link QEMU again without CONFIG_PARALLEL, the file should be considered for linking for all targets that have CONFIG_ISA_BUS. And while we're at it, add a proper comment in there with the rationale for the separate file.
