From: Takeshi Kihara <takeshi.kihara.df@renesas.com>

According to the R-Car Gen3 Hardware Manual Errata for Rev 1.00 of Aug
24, 2018, there is no need to configure MOD_SEL1 bit30 when the
SSI_SCK2_{A,B} or SSI_WS2_{A,B} pin functions are selected.

[geert: Remove now unused definitions, mark MOD_SEL1 bit30 reserved]
