No platforms enable the functionality to tftp directly to NOR flash, and
this is discouraged by the documentation.  Remove this code.  Further,
this highlights an oddity of the code.  Un-indent the start of this
function.

                If defined, hardware flash sectors protection is used

-- CONFIG_SYS_DIRECT_FLASH_TFTP:
-
-               Enable TFTP transfers directly to flash memory;
-               without this option such a download has to be
-               performed in two steps: (1) download to RAM, and (2)
-               copy from RAM to flash.
-
-               The two-step approach is usually more reliable, since
-               you can check if the download worked before you erase
-               the flash, but in some situations (when system RAM is
-               too limited to allow for a temporary copy of the
-               downloaded image) this option may be very useful.
-
 - CONFIG_SYS_FLASH_CFI:
                Define if the flash driver uses extra elements in the
                common flash structure for storing flash geometry.
