[IA64] Enable early console for Ski simulator
This patch cleans up the `enable early console for SKI' patch
(471e7a44848f467c9b83adc3463d019d2fa8817f), and
1. potentially allows the gensparse_defconfig to work again.
(there are other problems running a generic kernel on Ski)
2. fixes the `console registered twice' problem.
3. Cleans up the code by moving the `extern hpsim_cons' declaration to
a new asm/hpsim.h file.
Thanks to Jes for comments.
