SH-Mobile AG5 and R-Car H1 SoCs are based on the Cortex-A9 MPCore, which
includes a global timer.
Enable the ARM global timer on these SoCs, which will be used for:
- the scheduler clock, improving scheduler accuracy from 10 ms to 3 or
4 ns,
- delay loops, allowing removal of calls to shmobile_init_delay() from
the corresponding machine vectors.
Note that when using an old DTB lacking the global timer, the kernel
will still work. However, loops-per-jiffies will no longer be preset,
and the delay loop will need to be calibrated during boot.
