[Nokia] Update Nokia platform IXR7250E device data

[mlok-nokia]

Why I did it

Update Nokia platform IXR7250 platform_ndk.json files with the nokia_log_level option to allow users to override the logging level for the Nokia NDK processes -- sr_device_mgr, ndk-qfpga_mgr and eth_switch

How I did it

Modify the platform_ndk.json file with the following option. And default value is "error"

    {
      "key": "sonic_log_level",
      "stringval": "error"
    }

How to verify it

On running platform, verify the change by checking file /etc/opt/srlinux/startup_debug.json

admin@ixre-egl-board40:~$ cat /etc/opt/srlinux/startup_debug.json 
{
    "options": [
    {
        "key": "sfp_init_tx_en",
        "stringval": "yes"
    },
    {
        "key": "midplane_subnet",
        "stringval": "10.6.0.0/16"
    },
    {
        "key": "midplane_monitor",
        "stringval": "yes"
    },
    {
        "key": "monitor_action",
        "stringval": "reboot"
    },
    {
        "key": "grpc_thermal_monitor",
        "stringval": "yes"
    },
    {
        "key": "disable_vfio",
        "intval": 1
    },
    {
        "key": "sonic_bdb_mode",
        "intval": 0
    },
    { 
      "key": "update_asic_pvt",
      "intval": 10
    },
    {
      "key": "amd_pcon",
      "intval": 4
    },
    {
      "key": "enable_firmware_update",
      "intval": 0
    },
    {
      "key": "sonic_log_level",
      "stringval": "error"
    }
    ]
}
