hw/isa/vt82c686: Add missing Kconfig dependencies (build error)

The VT82C686 device model misses various dependencies:

  /usr/bin/ld: libcommon.fa.p/hw_isa_vt82c686.c.o: in function `vt82c686b_realize':
  hw/isa/vt82c686.c:622: undefined reference to `i8259_init'
  /usr/bin/ld: hw/isa/vt82c686.c:624: undefined reference to `i8257_dma_init'
  /usr/bin/ld: hw/isa/vt82c686.c:627: undefined reference to `mc146818_rtc_init'

Add them.
