ARM: shmobile: r8a7740: add MERAM work-around
r8a7740 chip has lasting errata on MERAM buffer, and this patch adds its work-around on setup-r8a7740.c It solved CEU/VIO6C/2D-DMAC/VCP1/VPU5F/JPU/DISP memroy access error. But MERAM driver can't control this issue, since this work-around requires access to non-MERAM register address. So, This it will be called as board specific code at this point.
