Subject: [PATCH] staging: sm750fb: add necessary #include in sm750_accel.h, sm750_cursor.h

In sm750_cursor.h, struct lynx_cursor is used without including the
header file where this struct is defined. Similar thing is seen in
sm750_accel.h.

The module can still be compiled because there is "#include "sm750.h""
before every "#include "sm750_accel.h"" and "#include "sm750_cursor.h"".
However, the order of #include should not affect the ability to compile.

Add "#include "sm750.h"" to sm750_accel.h and sm750_cursor.h.
