The drivers/gpu/host1x/context_bus.c does not include any declaration of
host1x_context_device_bus_type, and after including "context.h" it also
showed that there are two definitions in the kernel because the extern
declaration was missing the const qualifier.
Include linux/host1x_context_bus.h and drop the wrong declaration from
context.h. While at it, also predeclare struct host1x_memory_context.
Fixes the following sparse warning:
drivers/gpu/host1x/context_bus.c:9:23: warning: symbol 'host1x_context_device_bus_type' was not declared. Should it be static?
