parisc: Fix build of compressed kernel even with debug enabled

commit 3fe6c873af2f2247544debdbe51ec29f690a2ccf upstream.

With debug info enabled (CONFIG_DEBUG_INFO=y) the resulting vmlinux may get
that huge that we need to increase the start addresss for the decompression
text section otherwise one will face a linker error.
