Initial definitions for a simple machine using an AST2700 SOC (Cortex-a35 CPU).
AST2700 SOC and its interrupt controller are too complex to handle
in the common Aspeed SoC framework. We introduce a new ast2700
class with instance_init and realize handlers.
AST2700 is a 64 bits quad core cpus and support 8 watchdog.
Update maximum ASPEED_CPUS_NUM to 4 and ASPEED_WDTS_NUM to 8.
In addition, update AspeedSocState to support scuio, sli, sliio and intc.
Update silicon_rev data type to 64bits from AspeedSoCClass and
add TYPE_ASPEED27X0_SOC machine type.

When multiple devices output IRQ lines are connected to the same
input one, a IRQ OR gate has to be used.
