After changing all consumers of atomics to include <linux/atomic.h>, we
ran into some compile time errors due to this dependency chain:
linux/atomic.h
-> asm/atomic.h
-> asm-generic/atomic-long.h
where atomic-long.h could use funcs defined later in linux/atomic.h
without a prototype. This patches moves the code that includes
asm-generic/atomic*.h to linux/atomic.h.
Archs that need <asm-generic/atomic64.h> need to select
CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it
unconditionally).
Compile tested on i386 and x86_64 with allnoconfig.

Fix h8300's asm/atomic.h to store the IRQ flags in an unsigned long to deal
with warnings of the following type:
arch/h8300/include/asm/atomic.h: In function 'atomic_add_return':
arch/h8300/include/asm/atomic.h:22: warning: comparison of distinct pointer types lacks a cast
arch/h8300/include/asm/atomic.h:24: warning: comparison of distinct pointer types lacks a cast

In preparation for removing volatile from the atomic_t definition, this
patch adds a volatile cast to all the atomic read functions.

The existing asm-generic/atomic.h only defines the
atomic_long type. This renames it to atomic-long.h
so we have a place to add a truly generic atomic.h
that can be used on all non-SMP systems.
