[PATCH v3 1/3] maple: fix build error due to missing include of linux/device.h

The commit 313162d0b838 ("device.h: audit and cleanup users in main
include dir") removed the include linux/device.h from linux/maple.h,
which led to build errors as linux/maple.h embeds struct device via
struct maple_device. So restore this, as it otherwise results in errors:

./include/linux/maple.h:81:16: error: field 'dev' has incomplete type
  struct device dev;
