[PATCH 5.4 151/320] of: base: Fix phandle argument length mismatch error message

From: Baruch Siach <baruch@tkos.co.il>

[ Upstream commit 94a4950a4acff39b5847cc1fee4f65e160813493 ]

The cell_count field of of_phandle_iterator is the number of cells we
expect in the phandle arguments list when cells_name is missing. The
error message should show the number of cells we actually see.

Fixes: af3be70a3211 ("of: Improve of_phandle_iterator_next() error message")
