drm/rockchip: gem: Set size of the allocated object when create gem

Browse Source 
We may want to know how many size of a gem object is allocated, but
this size in rockchip_gem_object for no-IOMMU devices will not be set.

There are two ways to use rockchip GEMs, one is to create GEMs via DRM,
and the other is to import buffer created by other devices via DMA-BUF
and map it. For no-IOMMU devices, neither of them will set the buffer
size.

Let's set the size in rockchip_gem_object when we create a new rockchip
gem.

Fixes: c1c9524d3f ("drm/rockchip: debugfs: optimize dump buffer file name and size")
