I just pick-up Jacky's work, rebase and send out V4 based on
Jacky's V3 patchset.

If you prefer to split the patchset and send single patches, I could
resend one by one.

Note: the V3 has a gpio bindings patch, it has been seperated and
sent to gpio list in a single one per Linus requested.

This patchset is to add i.MX8ULP in dt-bindings, introduce
basic i.MX8ULP dtsi and basic evk board support.

The detailed version changes are in each patch.

There is checkpatch error in patch 8, but that is for device tree macro
and we could use use "(xx)".

In V4, the changes are in patch 8, 9 when rebasing to linux-next/master
,fix build errors after the clk driver in tree and drop a few nodes
that not have bindings.

Tested with CONFIG_CLK_IMX8ULP and CONFIG_PINCTRL_IMX8ULP enabled.
