12d6929e1f dm: x86: Set up interrupt routing from interrupt_init()
At present interrupt routing is set up from arch_misc_init(). We can do it
a little later instead, in interrupt_init().

This removes the manual pirq_init() call. Where the platform does not have
an interrupt router defined in its device tree, no error is generated. Some
platforms do not have this.

Drop pirq_init() since it is no-longer used.

f60df20aa9 x86: qemu: add fw_cfg support
The QEMU fw_cfg interface allows the guest to retrieve various data
information from QEMU. For example, APCI/SMBios tables, number of online
cpus, kernel data and command line, etc.

This patch adds support for QEMU fw_cfg interface.

7e4be120e8 x86: Allow pirq_init() to return an error
This function can fail. In this case we should return the error rather than
swallowing it.

eeae510007 x86: qemu: Support operation as an EFI payload
Disable a few things which interfere with the EFI init. This allows QEMU to
to boot into EFI, load a U-Boot payload then boot to the U-Boot prompt.
