By converting to the restart_notifier mechanism for restart, we allow
for other mechanisms, like the watchdog, to be used for restart in the
case where PS_HOLD has failed to reset the chip.
Since this mechanism may be one of several mechanisms registered, change
the post-ps_hold write timeout to be a more reasonable 1 second instead
of 10 seconds.
Choose priority 128, as according to documentation, this mechanism "is
sufficient to restart the entire system".

Currently the value used to specify that interrupts from the gpio should
be routed to the application processor is hardcoded for all Qualcomm SoCs.
But the new APQ8084 SoC uses a different value. To resolve this, we make
this value configurable for each SoC. For all existing SoCs we continue
to use the current value, and only for APQ8084 we use the new value.

commit 2243a87d90
"pinctrl: avoid duplicated calling enable_pinmux_setting for a pin"
removed the .disable callback from the struct pinmux_ops,
making the .enable() callback the only remaining callback.
However .enable() is a bad name as it seems to imply that a
muxing can also be disabled. Rename the callback to .set_mux()
and also take this opportunity to clean out any remaining
mentions of .disable() from the documentation.

This patch releases gpiochip related resources by calling
gpiochip_remove when either of gpiochip_add_pin_range and
gpiochip_irqchip_add fails.

We have four Qualcomm-related pin control drivers, and now there
are drivers coming in for the PMICs on these systems, so let's
create a qcom subdirectory to hold all the Qualcomm stuff.
