malta: Fix regression (i8259 interrupts did not work)
Commit
5632ae46d5bda798e971dae48ebb318ac2c3686a passes the address
of i8259 to qemu_irq_proxy. i8259 is an auto variable with undefined
value outside of mips_malta_init.
This made the interrupt proxy unusable: either QEMU crashes, or
the interrupt handler was not called.
Ethernet for example no longer worked with MIPS Malta.
v2:
While v1 used a static variable for i8259, this patch introduces
a qdev for the malta machine. i8259 is now part of the device status.
This is a minimal qdev implementation to keep the patch small.

configure: Fix test for supported host CPU type
The test for whether the host CPU is supported had several problems:
* the attempt to fall back to TCI was done as a duplicate
test, very late (so "--cpu foo" would fail early but "--cpu unicore32"
would fail late, differently, and after configure had already
printed a lot of output)
* a number of CPUs only supported as guests were included in the
list of CPUs we would accept as valid hosts, which would result
in a late compile failure on those systems rather than a
configure failure or fallback to TCI
* bailing out for an unsupported CPU happened before the main
option parsing, so "configure --help" wouldn't work
Fix these by folding the setting of ARCH into the first test for
supported host CPU, removing spurious guest-only CPU names from it,
and moving the "fall back to TCI" code earlier.
