[PATCH 2/2] mfd: palmas: get rid of of_platform_populate() in DT registration

[Laxman Dewangan <ldewangan@nvidia.com>]

If driver is getting registered through DT then it look for
population of platform data which is not possible if platform
completely support the DT.

In this case, if device is registered through DT then just ignore
platform data population and continue the further registration.
