Fixes IDE issues found on the Malta board under Qemu:
1) DMA implied commands were sent to the controller in stead of the PIO
variants. The rest of the code is DMA free and written for PIO operation.
2) direct pointer access was used to read and write the registers instead
of the inb/inw/outb/outw functions/macros. Registers don't have to be
memory mapped and ATA_CURR_BASE() does not have to return an offset from
address zero.
3) Endian isues in ide_ident() and reading/writing data in general. Names
were corrupted and sizes misreported.
Tested malta_defconfig and maltael_defconfig to work again in Qemu.

ATA commands are already defined in include/libata.h. There is no need to
duplicate them in include/ata.h.

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.

Writes in u-boot are so rare, and the logic to know when is
the last write and do a flush only there is sufficiently
difficult. Just do a flush after every write. This incurs,
usually, one extra flush when the rare writes do happen.

This patch adds support for the esd CPCI-HD/2 board to u-boot for CPCI-CPU/750.
As the primary devices on the CPCI-HD/2 board are connected to device 1 and 3,
the device must be swapped.

This patch adds a hook whereby a board-specific routine can be called to
configure hardware for a PIO mode. The prototype for the board-specific
routine is:
int inline ide_set_piomode(int pio_mode)
ide_set_piomode should be prepared to configure hardware for a pio_mode
between 0 and 6, inclusive. It should return 0 on success or 1 on failure.

This patch removes some enums from ata.h and replaces them with an
include of libata.h. This way, we eliminate duplicated code, and
prevent errors whereby the different versions could be out of sync.

Bridge, ICH-5, ICH-6 and ICH-7.
Implementation:
1. Code is divided in to two files. All functions, which are
controller specific are kept in "drivers/ata_piix.c" file and
functions, which are not controller specific, are kept in
"common/cmd_sata.c" file.
2. Reading and Writing from the S-ATA drive is done using PIO method.
3. Driver can be configured for 48-bit addressing by defining macro
CONFIG_LBA48, if this macro is not defined driver uses the 28-bit
addressing.
4. S-ATA read function is hooked to the File system, commands like
ext2ls and ext2load file can be used. This has been tested.
5. U-Boot command "SATA_init" is added, which initializes the S-ATA
controller and identifies the S-ATA drives connected to it.
6. U-Boot command "sata" is added, which is used to read/write, print
partition table and get info about the drives present. This I have
implemented in same way as "ide" command is implemented in U-Boot.
7. This driver is for S-ATA in native mode.
8. This driver does not support the Native command queuing and
Hot-plugging.
