ARM: shmobile: r8a7740: Remove restart callback

Remove the restart handling hack from the r8a7740 generic multiplatform
case.

Restart on DT-based r8a7740 platforms is now handled through the
R-Mobile reset driver.

This reverts commit 1174c712afa2779f ("ARM: shmobile: r8a7740: Add
restart callback").
