[PATCH 2/3] ARM: shmobile: r8a7740: Remove restart callback

[geert+renesas@glider.be (Geert Uytterhoeven)]

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").

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 aba07789d811b6cf ("ARM: shmobile: r8a7740 dtsi: Add PM domain
    support"), which is in v4.0-rc1,
  - "ARM: shmobile: Enable R-Mobile reset driver in multiplatform
    defconfig", which is the first patch of this series.
