[PATCH v2] ARM: imx: Re-introduce the PINCTRL selection

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

Since commit 17d210018914 ("ARM: imx: Allow user to disable pinctrl"),
the CONFIG_PINCTRL option is no longer implicitly selected, causing
several i.MX SoC pinctrl drivers no longer getting selected by default.

This causes boot regressions on the ARMv4, ARMv5, ARMv6 and ARMv7
i.MX SoCs.

Fix it by selecting CONFIG_PINCTRL as before.

This defeats the purpose of 7d210018914 ("ARM: imx: Allow user to disable
pinctrl"), but it is the less invasive fix for the boot regressions.

The attempt to build Layerscape without pinctrl can still be explored
later as suggested by Arnd:

"Overall, my best advice here is still to not change the way
i.MX pinctrl works at all, but just fix Layerscape to not depend
on i.MX. The reason for the 'select' here is clearly that the
i.MX machines would fail to boot without pinctrl, and changing
that because of Layerscape seems backwards."
