Just use the normal for_each_compatible instead.
Otherwise in the qemu model as executed by op-test,
we wouldn't go down the astbmc_init() path, thus not having flash.

A QEMU PowerNV machine does not necessarily have a BT device. It needs
to be defined on the command line with :
-device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10
When the QEMU platform is initialized by skiboot, we need to check
that such a device is present and if not, skip the AST initialization.

Back in 2016, we did not have a large support of the PowerNV devices
under QEMU and we were using our own custom ones. This has changed and
we can now use all the common init routines of the OpenPOWER
platforms.

It's possible for the platform to configure the BMC with SuperIO
access disabled. Rework the interfaces to report failures if SuperIO is
not enabled, and clean up once we're finished.

To access the PNOR, OPAL/skiboot drives the BMC SPI controller using
the iLPC2AHB device of the BMC SuperIO controller and accesses the
flash contents using the LPC FW address space on which the PNOR is
remapped.
The QEMU PowerNV machine now integrates such models (SuperIO
controller, iLPC2AHB device) and also a pseudo Aspeed SoC AHB memory
space populated with the SPI controller registers (same model as for
ARM). The AHB window giving access to the contents of the BMC SPI
controller flash modules is mapped on the LPC FW address space.
The change should be compatible for machine without PNOR support.

This changes to build system to use thin archives rather than
incremental linking for built-in.o, similar to recent change to Linux.
built-in.o is renamed to built-in.a, and is created as a thin archive
with no index, for speed and size. All built-in.a are aggregated into
a skiboot.tmp.a which is a thin archive built with an index, making it
suitable or linking. This is input into the final link.
The advantags of build size and linker code placement flexibility are
not as great with skiboot as a bigger project like Linux, but it's a
conceptually better way to build, and is more compatible with link
time optimisation in toolchains which might be interesting for skiboot
particularly for size reductions.
Size of build tree before this patch is 34.4MB, afterwards 23.1MB.

Adds a new structure that contains the implementations of the various
OPAL console handlers. This is intended to replace the existing ad-hoc
mechanism where the OPAL call handlers are overwritten in the OPAL
console driver's init function.
Currently this just moves the site where the OPAL call handlers are
overwritten to inside of console.c, but it is intended to give us a
mechanism for implementing features such as pointer validation for the
OPAL console calls without having to manually update each driver.
This also helps to clarify differences between the internal (skiboot)
console and the external (OPAL) console.

This brings the qemu platform to the level of an Open Power platform.
It adds the BT device used to communicate with the BMC using IPMI
messaging, power_downs and reboots the way OpenPower systems operate.
The device tree is also checked for UART and RTC device nodes and
updated if qemu has not defined them already. The initialization of
the BT and IPMI interfaces depends on the availability of the BT
device which needs to be explicitly defined by qemu. These tests
enable skiboot to maintain compatibility with previous versions of
qemu which did not update the device tree with enabled devices.

use common initialization, and clean up the device-tree

This adds support for running under qemu "powernv" platform, which
is currently available via the qemu repository at:
https://github.com/ozbenh/qemu branch "powernv"
qemu can't yet create DT entries for ISA devices so we hard wire the UART
and RTC devices in the device-tree like we do with other platforms.
