Add 1GHz to the r8a7779 DTS to describe the maximum CPU frequency.
Based on work by Magnus dam for the r8a7740 SoC.

Convert the common C-code-less r8a7779 DT board support
to use shmobile_init_delay() to be able to migrate away
from per-SoC delay setup functions.

already used for several over SoCs I will queue this up.
