u-boot stopped configuring 'non essential' pins recently. These pins are
essential for audio and need to be done to have working audio on the board.
Pin Mux configuration for: twl6040 audpwron gpio, McPDM, DMIC, McBSP1 and
McBSP2.

Let's see if that's possible to avoid mysterious bug reports
of things not working.
If we can't merge it, then it might be worth adding a warning
that bails out early after some pin is checked or similar.

With new enough u-boot the twl6040 fails to probe (mux for nirq2 and power
GPIO is not configured) which leads to no audio on OMAP4/5.
Adding another warning - and check - does not going to help to clarify the
situation IMHO.
We can still enable the CONFIG_SYS_ENABLE_PADS_ALL in u-boot and recompile it,
but this is disabled as default and to be frank there is no guaranty that this
is going to be available let's say next week.
