arm64: dts: imx8m: Reinstate TEE ifdeffery

Since b57ed147939c ("dts: imx8m{m,n,p,q}: Make optee packaging optional")
the TEE node is always present in U-Boot proper fitImage, even if the
CONFIG_OPTEE is disabled because the u-boot.itb should not contain any
tee.bin. This is wasteful, and produces the following warning which is
also confusing to users:

"
Image 'image' is missing optional external blobs but is still functional: tee-os

/binman/section/fit/images/tee/tee-os (tee.bin):
   See the documentation for your board. You may need to build Open Portable
   Trusted Execution Environment (OP-TEE) and build with TEE=/path/to/tee.bin
"

Reinstate the CONFIG_OPTEE ifdeffery to mitigate the problem, but retain the
binman "optional" keyword at tee.bin .

Before:
"
$ mkimage -l u-boot.itb
FIT description: Configuration to load ATF before U-Boot
Created:         Tue Jun 30 17:23:54 2026
 Image 0 (uboot)
...
 Image 2 (tee) <------------------------------ bogus empty image entry

  Compression:  uncompressed                           |

 Image 3 (fdt-1)

"

After:
"
$ mkimage -l u-boot.itb
FIT description: Configuration to load ATF before U-Boot
Created:         Tue Jun 30 17:58:15 2026

 Image 2 (fdt-1)
