Since commit 1b463bd51042927e ("ARM: dts: r8a7794: Rename the serial
port clock to fck") in v4.6, all upstream DTS files call the SCIF
functional clock "fck".
Hence the time is ripe to drop backward-compatibility with old DTBs that
use the old "sci_ick" name.

Note that such old DTBs have stopped working anyway since commit
58256143cff7c2e0 ("clk: renesas: Remove R-Car Gen2 legacy DT clock
support") in v5.5.
