configs/freescale_imx8mnevk: bump BSP components to lf-6.6.23-2.0.0

Bump ATF, U-Boot and Linux kernel to the NXP BSP lf-6.6.23-2.0.0
versions.

Also, since commit dc0f721 "package/gcc: switch to 13.x as default",
this freescale_imx8mnevk_defconfig is failing to build the Kernel
with output:

    drivers/mxc/gpu-viv/hal/os/linux/kernel/gc_hal_kernel_os.c:5769:1: error: conflicting types for '_QuerySignal' due to enum/integer mismatch; have 'gceSTATUS(struct _gckOS *, void *)' {aka 'enum _gceSTATUS(struct _gckOS *, void *)'} [-Werror=enum-int-mismatch]
     5769 | _QuerySignal(
          | ^~~~~~~~~~~~

This commit fixes the issue by updating the Kernel.

The BR2_GLOBAL_PATCH_DIR is also changed from
"board/freescale/common/patches" to
"board/freescale/imx8mnevk/patches". This for two reasons:

1. the common patch directory is removed, because the patches for
   arm-trusted-firmware are no longer needed. Patch 0001 is included
   in this new version, and patch 0002 no longer needed due a code
   rewrite in this new version. The common patch files are kept,
   because they are used in other freescale_ defconfigs.

2. the imx8mnevk patch directory is introduced, to include the needed
   hash files, because this commit enables
   BR2_DOWNLOAD_FORCE_CHECK_HASHES=y. Those hash files are introduced
   in a board specific directory to allow updating this defconfig
   independently of the other i.MX defconfigs: there is 16
   freescale_imx*_defconfigs, with more or less dependencies
   (firmwares, gpu drivers, ...). The ".checkpackageignore" entry for
   this defconfig is also removed.
