[PATCH v2 1/3] mtd: maps: vmu-flash: fix build error due to missing include of linux/device.h

Fix build error by adding the missing include of linux/device.h
linux/maple.h embeds struct device via struct maple_device, which
requires the definition. Otherwise results in build error:

./include/linux/maple.h:81:16: error: field 'dev' has incomplete type
  struct device dev;
                ^~~
./include/linux/maple.h:86:23: error: field 'drv' has incomplete type
  struct device_driver drv;
                       ^~~

Fixes: 313162d0b838 ("device.h: audit and cleanup users in main include dir")
