[PATCH v2 4/8] ARM: shmobile: genmai: Add RSPI children

From: Geert Uytterhoeven <geert+renesas at linux-m68k.org>
On this board, only rspi4 is in use. Its bus contains a single device
(a wm8978 audio codec).
As the RSPI driver itself doesn't use DT yet, we have to instantiate the
SPI child device in C code, too, for both genmai and genmai-reference.
