[PATCH 1/3] clocksource: sh_tmu: Document R-Mobile r8a7740 binding

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas at glider.be>

Compared to the r8a7779, the r8a7740 lacks the input capture register,
which is not used by the driver (the current driver already handles the
r8a7740 in the non-DT case).
