panfrost: Prepare things to avoid flushes on FB switch
panfrost_attach_vt_xxx() functions are now passed a batch, and the generated FB desc is kept in panfrost_batch so we can switch FBs without forcing a flush. The postfix->framebuffer field is restored on the next attach_vt_framebuffer() call if the batch already has an FB desc.
