core: arm: link.mk: produce tee-raw.bin by default

Adds tee-raw.bin as a dependency of all. This produces a tee-raw.bin for
all platforms when building. tee-raw.bin is more useful than for
instance tee-pager_v2.bin which often is used when a raw binary is
needed. Platforms with a link.mk only to produce tee-raw.bin have their
link.mk removed since the generic version suffices now.

core: imx: link: generate entry_point_address.txt for uTee image

For some platforms like mx7ulpevk, the `UL` attribute for CFG_DRAM_BASE
is necessary to avoid the following error:

core: imx: link: generate entry_point_address.txt for uTee image

For some platforms like mx7ulpevk, the `UL` attribute for CFG_DRAM_BASE
is necessary to avoid the following error:

$ PLATFORM=imx-mx7ulpevk make uTee
core/mm/mobj.c: In function ‘mobj_init’:
./out/arm-plat-imx/include/generated/conf.h:222:64: warning: integer overflow in expression of type ‘int’ results in ‘-1644167168’ [-Woverflow]
222 | #define CFG_TZDRAM_START (0x60000000 - 0x01e00000 - 0x00200000 + 0x40000000)
| ^

However, this `UL` attribute prevents the shell from properly computing
the CFG_TZDRAM_START value :

$ PLATFORM=imx-mx7ulpevk make uTee
bash: (UL(0x60000000) - 0x01e00000 - 0x00200000 + 0x40000000): missing `)' (error token is "(0x60000000) - 0x01e00000 - 0x00200000 + 0x40000000)")

To address both issues, remove the `UL` attribute from CFG_TZDRAM_START
with Makefile string substitution.

core: imx: generate uImage for imx6 and imx7 platforms

In the standard NXP BSP boot-flow, for imx6 and imx7 platforms (ARMv7),
optee-os is booted by U-Boot as a uImage file.
The generation of this uImage requires:
- optee-os load address. This address is fetched in the tee.elf file
with readelf.
- mkimage u-boot-tools. This tool takes the load address and the
tee-raw.bin as an input to generate the uImage uTee.

plat-imx, plat-rzn1: remove redundant recipes to generate tee-raw.bin

plat-imx, plat-rzn1: remove redundant recipes to generate tee-raw.bin

Since commit 5ae0290f7f3b ("core: kernel: link.mk: Move rules to generate
tee-raw.bin and tee.srec from rcar platform"), the recipe to produce
tee-raw.bin is in the common makefile core/arch/arm/kernel/link.mk.
Therefore the recipes in core/arch/arm/plat-imx/link.mk and
core/arch/arm/plat-rzn1/link.mk are redundant and need to be removed.
Fixes the following build warning:

$ make -s PLATFORM=imx-mx6ullevk
core/arch/arm/plat-imx/link.mk:7: warning: overriding recipe for target 'out/arm-plat-imx/core/tee-raw.bin'

We have observed that existing ARM-TF for iMX8QM treats OP-TEE binary
as headerless image. So, to create proper boot image we need raw

arm: imx: add i.MX 6UltraLite and EVK board support

The i.MX 6UltraLite[1] is a high performance, ultra-efficient processor
family featuring an advanced implementation of a single ARM® Cortex®-A7
core.

This patch add i.MX 6Ulralite EVK board support:
1. Add a uart driver for i.MX platforms
2. Introduce plat-imx for i.MX platforms
3. Introduce i.MX6 UltraLite platform
4. This patch has been tested using the following step,
4.1. build step:
PLATFORM_FLAVOR=mx6ulevk make ARCH=arm PLATFORM=imx
${CROSS_COMPILE}-objcopy -O binary out/arm-plat-imx/core/tee.elf optee.bin
copy optee.bin to the first partition of SD card which is used for boot.
4.2. Boot setting in uboot:
run loadfdt;
run loadimage;
fatload mmc 1:1 0x9c100000 optee.bin;
run mmcargs;
bootz ${loadaddr} - ${fdt_addr};
5. pass xtest

Note:
CAAM is not implemented now, this will be added later.
