common: update: fix an "unused" warning against update_flash()
Since update_flash() is used only in update_tftp(), it should be
guarded with appropriate config options.
After the commit 3149e524fc1e, common/update.c will be built under
either CONFIG_UDATE_TFTP, CONFIG_DFU_TFTP or CONFIG_UPDATE_FIT.
Since CONFIG_UPDATE_FIT, hence fit_update(), doesn't rely on
update_flash(), the compiler may cause an "unused" warning if
CONFIG_UPDATE_FIT=y and CONFIG_UPDATE_TFTP=n and CONFIG_DFU_TFTP=n.
This is, for example, the case for sandbox defconfig where
EFI_CAPSULE_FIRMWARE_FIT is enabled for test purpose.

sandbox: cros_ec: Basic support for EC_CMD_GET_NEXT_EVENT
Since commit 690079767803 ("cros_ec: Support keyboard scanning with
EC_CMD_GET_NEXT_EVENT") the cros-ec-keyb driver has started using this
command, but the sandbox EC emulator does not recognize it and
continuously prints:
** Unknown EC command 0x67
This patch makes the sandbox driver send basic responses to the command,
but the response only supports keyboard scans for now.
The EC side of this command stores and returns events from a queue, and
returns -EC_RES_UNAVAILABLE when there are no new events. This should be
possible to implement by hooking into the SDL event queue (perhaps via
sandbox_sdl_poll_events). Implementing that is a bit harder to do since
the existing sandbox code is discarding pending keyboard events, then
reading the current keyboard state.
Since the EC emulator never explicitly fails to work on this command,
the fallback to the older command will not trigger and will not be
tested anymore.
