Newer variants of Ixora boards require a power-up delay when powering up
the CAN transceiver of up to 1ms. This series adds mentioned delay for
iMX6 and iMX8 Apalis SoM variants.

Why is only the iMX6 change required for stable?

From what I know currently apalis-imx8 is not yet used in products
with a mainline kernel therefore the assumption that the backporting
would add very small value, however maybe is better to just backport
both to stable.
