Don't try to attach mac to device if there is no net support selected.
Fixes:
undefined reference to `dev_add_param_mac' in both iim and ocotp drivers.

ARM: i.MX: iim: Add regulator support ...

The voltage for programming the fuses is external to the SoC and
on some boards this is controllable with a regulator, so add regulator

ARM i.MX: IIM rework ...

The IIM module uses two drivers, one for the general IIM
module and one for the individual banks.
This patch turns this into a single driver to ease registration
of the resources. This changes the user visible behaviour in
the way that the explicit_sense_enable and permanent_write_enable
device parameters are no longer bank specific but for the
whole device. Also, the IIM module supports a maximum of
8 fuse banks, with these patch all of them are registered, even
if they are not present in a SoC.
