sparc: Fix /proc/kcore 

/proc/kcore investigates the "System RAM" elements in /proc/iomem to
initialize it's memory tables.  Therefore we have to register them
before it tries to do so.  kcore uses device_initcall() so let's
use arch_initcall() for the registry.

Also we need ARCH_PROC_KCORE_TEXT to get the virtual addresses of
the kernel image correct.
