Staging: dream: remove dream driver and arch from tree

This code is stalled, with no one working on it anymore, and the main
msm code is now going through the proper channels to get merged
correctly.

So remove it as it contains a number of kernel information leaks and it
is doubtful if it even still builds anymore.

-* camera driver uses old V4L API
-
-* coding style in some places is lacking
-
-* gpio_input.c has some features matrix_keypad lacks. They should be
-merged to gpio_input, with gpio_input.c removed
-
-* pmem provides interface for userspace. Needs to be reviewed at least.
-
-* it is probably possible to simplify touchscreen driver using threaded_irq's.
-
-* touchscreen driver should be switched to oficial multitouch API
