soc: renesas: Enable ARM_ERRATA_754322 for affected Cortex-A9
ARM Erratum 754322 affects Cortex-A9 revisions r2p* and r3p*. Automatically enable support code to mitigate the erratum when compiling a kernel for any of the affected Renesas SoCs: - RZ/A1: r3p0, - R-Mobile A1: r2p4, - R-Car M1A: r2p2-00rel0, - R-Car H1: r3p0, - SH-Mobile AG5: r2p2. EMMA Mobile EV2 (r1p3) and RZ/A2 (r4p1) are not affected. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Simon Horman <horms+renesas@verge.net.au>
