4c25f365ab cpu/a9mpcore: reorder operations/declarations
To make it consistent for easier code reading. The order in which
variables are defined and functions are called is set to match the
address map ordering.

The new consistent order of doing stuff is:

SCU -> GIC -> MPTimer -> WDT.

0 functional change.

66aae5e1ec default-configs: Fix A9MP and A15MP config names
When individual CONFIG_ switches for the A9MPcore and A15MPcore
devices were created, they were inadvertently given incorrect names
(CONFIG_ARM9MPCORE and CONFIG_ARM15MPCORE). These CPUs are
"Cortex-A9MP" and "Cortex-A15MP", and in particular the ARM9 is
a different (rather older) CPU than the Cortex-A9. Rename the
CONFIG_ switches to bring them into line with the source file
names and CPU names.

528622421e hw/cpu/a15mpcore: Correct default value for num-irq
The a15mpcore device claims that its default value for num-irq
is the number of interrupts used by the A15MP in the vexpress-a15
board. However that chip has 128 external interrupts, not 64.
Since there is only one A15 based model in QEMU currently, we
can fix this by simply changing the default value.

This error was causing recent (3.10) Linux kernels to print
warnings/backtraces when the number of interrupts reported
by the GIC was smaller than an interrupt number they wanted
to use.
