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.
