nand: Sync with Linux v4.1

Update the NAND code to match Linux v4.1. The previous sync was

CONFIG_SYS_NAND_RESET_CNT is removed, as the upstream Linux code now
has its own timeout. Plus, CONFIG_SYS_NAND_RESET_CNT was undocumented
and not selected by any board.

In addition to mtd_block_isbad(), which checks if a block is bad or

mtd_block_isbad().

While here, fix mtd_block_isbad() so the out-of-bounds checking is done
before the callback check.

linux/kconfig.h: add CPP macros useful for per-image config options

The previous commit introduced a useful macro used in makefiles,
in order to reference to different variables (CONFIG_... or
CONFIG_SPL_...) depending on the build context.

Per-image config option control is a PITA in C sources, too.
Here are some macros useful in C/CPP expressions.

CONFIG_IS_ENABLED(FOO) can be used as a shorthand for

(!defined(CONFIG_SPL_BUILD) && defined(CONFIG_FOO)) || \
(defined(CONFIG_SPL_BUILD) && defined(CONFIG_SPL_FOO))

For example, it is useful to describe C code as follows,

#if CONFIG_IS_ENABLED(OF_CONTROL)
(device tree code)
#else
(board file code)
#endif

The ifdef conditional above is switched by CONFIG_OF_CONTROL during
the U-Boot proper building (CONFIG_SPL_BUILD is not defined), and by
CONFIG_SPL_OF_CONTROL during SPL building (CONFIG_SPL_BUILD is
defined).

The macro can be used in C context as well, so you can also write the
equivalent code as follows:

if (CONFIG_IS_ENABLED(OF_CONTROL)) {
(device tree code)
} else {
(board file code)
}

Another useful macro is CONFIG_VALUE().
CONFIG_VALUE(FOO) is expanded into CONFIG_FOO if CONFIG_SPL_BUILD is
undefined, and into CONFIG_SPL_FOO if CONFIG_SPL_BUILD is defined.

You can write as follows:

text_base = CONFIG_VALUE(TEXT_BASE);

instead of:

#ifdef CONFIG_SPL_BUILD
text_base = CONFIG_SPL_TEXT_BASE;
#else
text_base = CONFIG_TEXT_BASE;
#endif

This commit also adds slight hacking on fixdep so that it can
output a correct list of fixed dependencies.

If the fixdep finds CONFIG_IS_ENABLED(FOO) in a source file,
we want
$(wildcard include/config/foo.h)
in the U-boot proper building context, while we want
$(wildcard include/config/spl/foo.h)
in the SPL build context.

linux_compat: handle __GFP_ZERO in kmalloc()

Currently, kzalloc() returns zero-filled memory, while kmalloc()
simply ignores the second argument and never fills the memory
area with zeros.

I want kmalloc(size, __GFP_ZERO) to behave as kzalloc() does,
which will make it easier to add more memory allocator variants.

With the introduction of __GFP_ZERO flag, going forward, kzmalloc()
variants can fall back to kmalloc() enabling the __GFP_ZERO flag.

The macro cpu_relax() is defined by several headers in different
ways.

arch/{arm,avr32,mips}/include/asm/processor.h defines it as follows:
#define cpu_relax() barrier()

On the other hand, include/linux/compat.h defines it as follows:
#define cpu_relax() do {} while (0)

If both headers are included from the same source file, the warning
warning: "cpu_relax" redefined [enabled by default]
is displayed.

It effectively makes it impossible to include <linux/compat.h>
from some sources. Drop the latter.
