NAND flavors, like serial and parallel, have a lot in common and would
benefit to share code. Let's move raw (parallel) NAND specific code in a
raw/ subdirectory, to ease the addition of a core file in nand/ and the
introduction of a spi/ subdirectory specific to SPI NANDs.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

This header was renamed to rawnand.h in Linux.
The following is the corresponding commit in Linux.

mtd: nand: Rename nand.h into rawnand.h
We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.

I largely reworked the Denali NAND controller driver in Linux.
This commit imports the improvements from Linux. The code is
almost synced with Linux 4.15-rc1.

Updates the NAND code to match Linux v4.6. The previous sync was from
Linux v4.1 in commit d3963721d9.
Note that none of the individual NAND drivers tracked Linux closely
enough to be synced themselves, other than manually applying a few
cross-tree changes.

Since commit 2580a2a7e7 ("mtd: nand: Increase max sizes of OOB and
Page size"), three boards (ph1_ld4, ph1_pro4, ph1_sld8) fail to build
with the following error message:
arm-linux-gnueabi-ld.bfd: SPL image plus BSS too big
They compile drivers/mtd/nand/denali_spl.c and it has a page_buffer
as static data:
static uint8_t page_buffer[NAND_MAX_PAGESIZE];
This buffer required 8KB in .bss section before that commit and now
it has been increased to 16KB. Given limited code/memory size for SPL,
it is not a good idea to allocate a page buffer statically. In the
first place, the load address 'dst' can be used as a page buffer.

U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does. This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.
Many of references of those macros must be fixed to suppress warnings.
We have two options:
- Use min, max, min3, max3 only when the arguments have the same type
(or add casts to the arguments)
- Use min_t/max_t instead with the appropriate type for the first
argument

The SPL-mode driver for Denali(Cadence) NAND Flash Memory Controller IP.
This driver requires two CONFIG macros:
- CONFIG_SPL_NAND_DENALI
Define to enable this driver.
- CONFIG_SYS_NAND_BAD_BLOCK_POS
Specify bad block mark position in the oob space. Typically 0.
