media: atmel: move microchip_csi2dc to dedicated microchip platform

The Atmel ISC will be moved to staging thus the atmel platform will only
have the ISI driver.
The new media-controller converted ISC driver will be placed inside a
dedicated microchip platform directory.
It is then natural to have the microchip-csi2dc moved to this new platform
directory.
The next step is to add the Microchip ISC driver to the new platform
directory and reside together with the Microchip CSI2DC driver.
