No, this driver is not for ARCH_OMAP*, but for TI bandgap, with the
option to offer thermal control. So, the HW supported is TI bandgap IP,
not ARCH_OMAP*. It happens to be so that OMAP2PLUS all have a
(different) version of this device.

However, DRA7 devices, for instance, also feature the bandgap IP
(different version of those present in OMAP devices), and it is not
ARCH_OMAP2PLUS.

And because of that, the design of this driver is different. It is not
expected to depend on an arch, but the arch code is expected to select
ARCH_HAS_BANDGAP.
