Get rid of KZM9D board code written in C. This version of the C board code was used in the case of multiplatform, but these days DT can be used instead, so because of that simply get rid of the C code to simplify and save space.

Ether MAC is a DMA-capable device and so should have 'dev.dma_mask' and 'dev.coherent_dma_mask' fields set properly, to reflect 32-bit DMA addressing ability. Currently, the code works without DMA masks but as we would have to enable CONFIG_HIGHMEM to access the full board memory in the future, when support for NETIF_F_SG would be added to the 'sh_eth' driver as well, the correct DMA masks should start to matter...

Remove ifdefs to make the Lager USBHS device always present. This makes it more like other devices, no need to be special. Also, these ifdefs by themselves do not hurt much, but combined with USB Host device ifdefs that were proposed earlier we could basically end up with a kernel that drives VBUS incorrectly depending on the kernel configuration - lets not do that.
