grlib_irqmp_create(), grlib_gptimer_create() and
grlib_apbuart_create() are helpers to create and realize GRLIB
devices.  Their only caller leon3_generic_hw_init() doesn't check for
failure.  Only the first can actually fail, and only when the caller
fails to set up a pointer property, which is a programming error.

Replace qdev_init() by qdev_init_nofail().

firmware_abi.h with structs for OpenBIOS landed in hw/sparc/ by mistake
- move it to hw/nvram/ alongside fw_cfg.h.  In addition to sparc it's
included from ppc mac_nvram.c and will need to include it from prep.c in
the future.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.
