Subject: drm/vmwgfx: Limit max desktop dimensions to 8Kx8K

From: Sinclair Yeh <[email protected]>

commit 7b009e76797c82178d7a03ae0eaad5951d975277 upstream.

This was originally chosen to be an arbitrarily large number. However, some user mode may actually try to set a 16Kx16K mode and run into other issues.

Since 8Kx8K is the current texture limit for Mesa LLVM driver, we will just use this limit for now.
