powerpc/eeh_cache: fix a W=1 kernel-doc warning

Browse source 
The opening comment mark "/**" is reserved for kernel-doc comments, so
it will generate a warning with "make W=1".

arch/powerpc/kernel/eeh_cache.c:37: warning: cannot understand function
prototype: 'struct pci_io_addr_range

Since this is not a kernel-doc for the struct below, but rather an
overview of this source eeh_cache.c, just use the free-form comments
kernel-doc syntax instead.
