x86/EISA: Don't probe EISA bus for Xen PV guests
...
For unprivileged Xen PV guests this is normal memory and ioremap will
not be able to properly map it.
While at it, since ioremap may return NULL, add a test for pointer's
validity.

x86/boot: Move EISA setup to a separate file
...
EISA has absolutely nothing to do with traps, so move it out of traps.c
into its own eisa.c file.
Furthermore, the EISA bus detection does not need to run during
very early boot, it's good enough to run it before the EISA bus
and drivers are initialized.
I.e. instead of calling it from the very early trap_init() code,
make it a subsys_initcall().
