[Buildroot] [PATCH 2/2] configs/imx8mpico: bump bsp components to version tn-hardknott_5.10.72-2.2.0

[Julien Olivain <ju.o@free.fr>]

Those components are aligned with NXP BSP lf-5.10.72-2.2.0.

This commit also refresh the readme.txt file:
- update no longer working URLs,
- enhance flashing instructions (use ${mmcdev} uboot variable),
- add "bs=1M" option to dd for better flashing performances.

Fixes:
