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

[Geert Uytterhoeven <geert-Td1EMuHUCqxL1ZNQvxDV9g@public.gmane.org>]

From: Geert Uytterhoeven <geert+renesas-Td1EMuHUCqxL1ZNQvxDV9g@public.gmane.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.
