All modes exposed by simple panels should be tagged as driver defined

obviously the preferred one.

Doing this also fix a problem occurring when a 'video=' parameter is
passed on the kernel command line. In some cases the user provided mode
will be preferred over the simple panel ones, which might result in
unpredictable behavior.

   - use generic functions - gem_prime_mmap and dma_buf_mmap.
   - use DMA-Mapping API instead of specific one.
   - some code cleanups and fixeups.

Actually, pp_sw_init executes pptable_init and backend_init orderly if
they are initialized successfully. So rewrite it to make code more
readable.
