mesa: Re-enable dri driver swrast for NXP BSP

Seems swrast won't disable hardware acceleration and is still needed to prevent
a build break in xserver-xorg.

```
| Package dri was not found in the pkg-config search path.
| Perhaps you should add the directory containing `dri.pc'
| to the PKG_CONFIG_PATH environment variable
| No package 'dri' found
```
