[PATCH v3 02/15] libfdt: overlay: Drop redundant *sep != ':' checks after memchr()

[Douglas Anderson <dianders@chromium.org>]

In `overlay_fixup_phandle()`, `sep` is obtained via `memchr(..., ':',
...)`. When `sep` is non-NULL, `*sep` is guaranteed to be `':'`, so the
`|| *sep != ':'` checks are redundant. Drop them.

Changes in v3:
- Split the removal of redundant *sep != ':' checks out of "libfdt:
  overlay: Prepare fixup and fragment path helpers for reuse" into a
  standalone patch
