ARM: at91: add AT91_SAM9_TIME entry to select at91sam926x_time.c compilation

No more associate at91sam926x_time.c compilation with SOC_AT91SAM9 entry since
SAMA5D3 devices will use this driver too.

ARM: at91: introduce the core type choice to split ARMv4/5 and ARMv7 arch

As we will introduce SAMA5, we need to distinguish the core architecture. It is

ARM: at91: introduce SAMA5 support

requirement since some peripherals can't work at the bus frequency on SAMA5.
