[PATCH v3 01/17] common: update_tftp: remove unnecessary build check

[AKASHI Takahiro]

Logically, the current update_tftp() should and does compile and work
correctly even without satisfying the following condition:

> #if defined(CONFIG_UPDATE_TFTP) && !defined(CONFIG_MTD_NOR_FLASH)
> #error "CONFIG_UPDATE_TFTP and !CONFIG_MTD_NOR_FLASH needed for
>  legacy behaviour"
> #endif

It would be better to just drop it so that this function will be
used on wider range of platforms.
