[v3,02/17] dfu: add a hidden reverse-dependency on UPDATE_TFTP

DFU_OVER_TFTP support on "dfu" command relies on update_tftp()
being available. Just explicitly add this dependency.

UPDATE_TFTP depends on FIT while DFU_OVER_TFTP does not depend on FIT.

So selecting UPDATE_TFTP without FIT creates an invalid configuration:

Symbol: UPDATE_TFTP [=y]
Type  : bool
Prompt: Auto-update using fitImage via TFTP
  Location:
(1) -> Update support
  Defined at common/Kconfig:1017
  Depends on: FIT [=n]
  Selected by [y]:
  - DFU_OVER_TFTP [=y] && NET [=y]

WARNING: unmet direct dependencies detected for UPDATE_TFTP
  Depends on [n]: FIT [=n]
  Selected by [y]:
  - DFU_OVER_TFTP [=y] && NET [=y]

common/update.c: In function ?update_fit_getparams?:
common/update.c:220:6: error: implicit declaration of function
?fit_image_get_data?; did you mean ?image_get_data??
[-Werror=implicit-function-declaration]
  220 |  if (fit_image_get_data(fit, noffset, &data, (size_t *)size))

The whole UEFI capsule update development should not depend on NET and
hence not on UPDATE_TFTP.
