Replace calls to exynos_drm_gem_get_{dma_addr,size}, by a simpler
function exynos_drm_gem_get(). This lets the caller to get access to
exynos_drm_gem object and extract any information about GEM object
without searching object tree for getting each parameter.

This patch forces all GEM buffers to have pitch aligned at least to 8
pixels. This is a common requirement for various Exynos IPP blocks,
which otherwise won't be able to operate on buffers of random size.

Add framebuffer pointer to exynos_drm_plane_state and tell drivers to use
it. This lets common plane code to set temporary framebuffer in the
future and drivers will use it without additional changes.

This patch fixes trashed display of buffers cropped to very small width.
Even if DMA is unstable and causes tearing when changing the burst size,
it is still better than displaying a garbage.

This patch fixes calculation of src x/y offset for negative crtc x/y

This patch adds generic check for plane state - display area dimensions,
so drivers can always assume that they get valid plane state to set.

DMA address is a framebuffer attribute and the right place for it is
exynos_drm_framebuffer not exynos_drm_plane. This patch also introduces
helper function for getting dma address of the given framebuffer.
