[PATCH 1/2] spi: sh-msiof: Add rcar fallback compatibility string

[Yoshihiro Kaneko <ykaneko0929@gmail.com>]

Add fallback compatibility string for R-Car Gen2 and Gen3.
This is in keeping with the fallback scheme being adopted wherever
appropriate for drivers for Renesas SoCs.
In Addition, this patch deletes the compat strings for old SoCs.
