Some of the stuff in /proc/ppc64 such as the RTAS bits are actually
useful to some 32-bit platforms. Rename the file, and create a
symlink on 64-bit for backward compatibility

Simply replace proc_create and further data assigned with proc_create_data.
No need to check for data!=NULL after that.

In pseries/lpar.c, fix some printf specifier mismatches, and add
a newline to one printk.
In pseries/rtasd.c add "rtasd" to some messages to make it clear
where they're coming from.
In pseries/scanlog.c remove the hand-rolled runtime debugging support
in there. This file has been largely unchanged for eons, if we need to
debug it in future we can recompile.

scanlog_init() could use some love.
* properly return -ENODEV if this system doesn't support scan-log-dump
* don't printk if scan-log-dump not present; only older systems have it
* convert from create_proc_entry() to preferred proc_create()
* allocate zeroed data buffer
* fix potential memory leak of ent->data on failed create_proc_entry()
* simplify control flow

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to
these shared resources.

Export both news RTAS delay functions, and change the scanlog module to
use the new delay functions.

These symbols are only used in the file that they are defined in,
so they should not be in the global namespace.

scanlog.c is only compiled on pSeries. Thus, this patch moves it to
platforms/pseries.
Built and booted on pSeries LPAR (ARCH=powerpc and ARCH=ppc64). Built
for iSeries (ARCH=powerpc).
