If the system is built for big endian, then the CPU identificaiton register
will be read in the wrong order. Fix this by using readl_relaxed() on the
register.

It's useful to get the CPU ID/rev printed during boot sometimes, so
add a line with that information. Given that the fields have moved
within the register over time, don't try to be clever and parse it --
just print the raw values for now.

After refactoring suspend/resume, which was last part with dependencies
on legacy code, all Kconfig symbols related to Samsung ATAGS support can
be deselected and more unused code removed. This includes most of s5p-*
code as well, as s5pv210 was their last user.

This makes it possible to enable the s5pv210 platform as part of a
multiplatform kernel. Also redundant Kconfig options are removed.

The function is nearly empty and samsung_cpu_rev is static
so already 0 making the function obsolete, therefore remove
it.
