Enable ADV7280 decoder for iMX6 modules. ADV7280 and ADV7180 have
same addresses viz. 0x21 respectively, changing the ADV7280 address
to 0x20 would result in a conflict with MAX9526. As a result enable
ADV7280 by default and disable ADV7180.

The main i.MX 7 SoC compatible string is fsl,imx7d. By that compatible
string, the whole machine init in mach-imx7d.c is registered. While
some might not be necessary for i.MX 7Solo (e.g. SMP init), it seems
not to hurt. On the other hand, not using the i.MX 7 machine init
bypasses a lot of low level init such as PM or basic ethernet clocking.
So far it seemed not to have caused negative effects (likely since the
bootloader initialized those stuff already reasonable...).

Commit 619c5719cf ("MLK-11566-7 ARM: imx: support single SOC config")
ifdef'd clock functionality for SoloX only if Cortex-M4 is running.
However, i.MX 7 also provides a Cortex-M4, hence the true branch in
those if statements have been taken. Since the whole block was ifdef'd,
the functions were rendered useless for i.MX 7. Fix this by just
doing the same thing as if Cortex-M4 is not running.

If poweroff takes a bit more time (e.g. due to I2C call), it is
quite likely that another timer interrupt fires. Timer interrupt
get broadcasted through the timer interrupt callback
tick_handle_oneshot_broadcast. This code broadcasts the timer
interrupt to all CPU's in tick_broadcast_oneshot_mask. The only
function which removes CPU from this mask is
tick_shutdown_broadcast_oneshot which ultimately get called by
_cpu_down (in kernel/cpu.c). The function disable_nonboot_cpus
makes sure that the CPU's get properly taken down and _cpu_down
gets called. With that no more broadcasts are sent to CPU's which
are no longer online.

from an external circuit.

The invalid value of #address-cells in the imx6 pcie host controller node
causes of_irq_parse_raw() to incorrectly advance through an interrupt-map
table of more than one interrupt. We also take the opportunity to drop the
unused #size-cells here.
This patch resolves this issue and allows proper interrupt mapping for an
imx6 pcie host connected to a P2P bridge when using legacy interrupts.

With the 3.14.28 release of the kernel imx6_stop_mode_poweroff() does not
enter stop mode.
Thus the function does not switch of power but returns.
This seems to be caused by the second processor which has been stopped.
Set the WFI event mask for the stopped processor works around the issue.
