ARM: i.MX7: drop now useless imx7s.dtsi ...

This file was introduced in commit 55eed47d8515 ("ARM: i.MX7: Add
imx7s.dtsi") because the imx clocksource driver picked the wrong clock
to determine the parent frequency. As this is fixed since commit
"ARM: imx: clocksource: Use per clock for determining parent freq" this
file can go away.

ARM: imx: clocksource: Use per clock for determining parent freq ...

For imx1, imx25, imx27, imx31, imx35 and imx5x this doesn't make a
difference because clk_get(dev, NULL) returns the same clock as
clk_get(dev, "per") because the id parameter isn't checked at all and
the per clock is returned unconditionally.

For imx6sl, imx6sx and imx6ul different clocks are returned, but both
are gates for "perclk". For imx6qdl clk_get(..., NULL) returns
IMX6QDL_CLK_GPT_IPG which is a gate of "ipg", while clk_get(..., "per")
returns IMX6QDL_CLK_GPT_IPG_PER which is a gate of "ipg_per" which in
turn is a divider of "ipg" with a boot-up default value of 1 which isn't
touched in barebox.

So the only SoC where this change matters is imx7 where clk_get(dev,
NULL) returns a dummy clk while clk_get(dev, "per") returns the right
clk to use.
