imx6: Add and use Kernel 5.10.32 for Yocto Hardknott
With the recent adaption it is possible to build the iMX6 based G&F platforms with the latest LTS kernel version 5.10.32.
Thus change the preferred Linux kernel version to 5.10.32. Use a weak assignment to be able to override this in the local.conf.
