NXP BSP release LF5.15.52_2.1.0

Hi Otavio, Hi Tim

NXP released a new revision LF5.15.52_2.1.0 of their BSP [1].

What is the plan to update the recipes in meta-freescale to the versions
used by LF5.15.52_2.1.0? Can we start to send pull requests?

Will kirkstone stay on LF5.15.32_2.0.0 or will we backport whatever is
done for LF5.15.52_2.1.0 also to kirkstone?
