nvidia-tegra-defaults (1.4~24.04.2) noble; urgency=medium

  * Fix support for Thor systems (LP: #2127100)
    - Modify the debian/nvidia-tegra-defaults.postinst to remove a chmod of
      /dev/tpmrm0 introduced in the previous update that is not required.
    - Update the default cmdline to prepare support for Thor systems.

Bug description:
  [ Impact ]

   * The new Thor platform requires an additional kernel command line
  parameter to properly function. The nvidia-tegra-defaults is already
  responsible for some specific kernel cmdline setup, adding these here
  will enable this new hardware.

   * While implementing these fixes, we realized a chmod was pushed
  previously in postinst that shouldn't be there.

  [ Test Plan ]

   * Booting a Thor platform without this patch is not possible if there
  is not another workaround implemented. Booting the board with a noble
  image including this package without any manual change of the kernel
  command line must work.

  [ Where problems could occur ]

   * Thor platforms could still not work if these kernel parameters are
  not enough.
