arm: imx: hab: Add IVT header definitions
The various i.MX BootROMs containing the High Assurance Boot (HAB) block
rely on a data structure called the Image Vector Table (IVT) to describe to
the BootROM where to locate various data-structures used by HAB during
authentication.
This patch adds a definition of the IVT header for use in later patches,
where we will break the current incorrect dependence on fixed offsets in
favour of an IVT described parsing of incoming binaries.

arm: imx: hab: Fix authenticate_image input parameters
u-boot command "hab_auth_img" tells a user that it takes
- addr - image hex address
- offset - hex offset of IVT in the image
but in fact the callback hab_auth_img makes to authenticate_image treats
the second 'offset' parameter as an image length.
Furthermore existing code requires the IVT header to be appended to the end
of the image which is not actually a requirement of HABv4.
This patch fixes this situation by
1: Adding a new parameter to hab_auth_img
- addr : image hex address
- length : total length of the image
- offset : offset of IVT from addr
2: Updates the existing call into authenticate_image() in
arch/arm/mach-imx/spl.c:jump_to_image_no_args() to pass
addr, length and IVT offset respectively.
This allows then hab_auth_img to actually operate the way it was specified
in the help text and should still allow existing code to work.
It has the added advantage that the IVT header doesn't have to be appended
to an image given to HAB - it can be prepended for example.
Note prepending the IVT is what u-boot will do when making an IVT for the
BootROM. It should be possible for u-boot properly authenticate images
made by mkimage via HAB.
This patch is the first step in making that happen subsequent patches will
focus on removing hard-coded offsets to the IVT, which again is not
mandated to live at the end of a .imx image.

To support QSPI DM driver
- Add spi0 alias for qspi node. Which is used for bus number 0.
- Modify the n25q256a@0 compatible property to "spi-flash".
- Modify spi4 (gpio_spi) node to spi5
- Define DM SPI/QSPI related config to enable QSPI

spi: fsl_qspi: support i.MX6UL/6ULLL/7D
The QSPI module on i.MX7D is modified from i.MX6SX. The module used on
i.MX6UL/6ULL is reused from i.MX7D. They share same tx buffer size.
The endianness is not set at qspi driver initialization. So if we don't
boot from QSPI, we will get wrong endianness when accessing from AHB
address directly.
Add the compatible entry for 6ul/7d.
