ASoC: ab8500: Inform SoC Core that we have our own I/O arrangements
If codec->control_data is not populated SoC Core assumes we want to
use regmap, which fails catastrophically, as we don't have one:
Unable to handle kernel NULL pointer dereference at virtual address 00000080
pgd = c0004000
[00000080] *pgd=00000000
Internal error: Oops: 17 [#1] PREEMPT SMP ARM
