ARM: shmobile: Always enable ARCH_TIMER on SoCs with A7 and/or A15
R-Mobile APE6, R-Car Gen2, and RZ/G1 SoCs have Cortex-A7 and/or
Cortex-A15 CPU cores, all of which have ARM architectured timers.
Force use of the ARM architectured timer on these SoCs.
This allows to:
- Remove the calls to shmobile_init_delay() from the corresponding
machine vectors,
- Remove a check in timer setup specific to R-Car Gen2,
- Remove a check in shmobile_init_delay().
