[PATCH 3/3] ARM: shmobile: sh73a0: Remove restart callback

[Geert Uytterhoeven]

Remove the restart handling hack from the sh73a0 generic multiplatform
case.

Restart on DT-based sh73a0 platforms is now handled through the
R-Mobile reset driver.

This basically reverts commit cad900819fba0176 ("ARM: shmobile: sh73a0:
Add restart callback").

To avoid losing functionality, this depends on:
  - commit fa0f8d6700857457 ("power: reset: Add reset driver for
    R-Mobile platforms"), which is in v4.0-rc1,
  - commit 126693a80f451ecd ("ARM: shmobile: sh73a0 dtsi: Add PM domain
    support"), which is in sh73a0-multiplatform-for-v3.21,
  - "ARM: shmobile: Enable R-Mobile reset driver in multiplatform
    defconfig", which is the first patch of this series.
