The default power limit read from the SPLC method in ACPI doesn't
have anything to do with the transport and is only used in the opmode,
so we can remove it from the trans.  Additionally, this value is only
user when the opmode is starting, so we don't need to store it
anywhere.

Remove the dflt_pwr_limit element from the trans and move call to
iwl_acpi_get_pwr_limit() call to mvm.

Move most of the set_dflt_pwr_limit() function to acpi.c and make it

There are many places where the same process of invoking a method from
ACPI is used, causing a lot of duplicate code.  To improve this,
introduce a new function to get an ACPI object by invoking an ACPI
method that can be reused.

Additionally, since this function needs to be called when we only have
the trans, the opmode or the device, introduce a new debug macro that
gets the device as a parameter so it can be used in the new function.

When going into suspend, the HW configuration for MSI-X will
likely be lost. As a consequence, after waking up, all IRQ
causes will be mapped to interrupt 0, and as a consequence we
don't notice the interrupt because in most cases this is an
interrupt for a queue, and getting it doesn't read the other
cause registers.

When toggling the RF-kill pin quickly in succession, the driver can
get rather confused because it might be in the process of shutting
down, expecting all commands to go through quickly due to rfkill,
but the transport already thinks the device is accessible again,
even though it previously shut it down. This leads to bugs, and I
even observed a kernel panic.

Avoid this by making the PCIe code only report that the radio is
enabled again after the higher layers actually decided to shut it
off.

This also pulls out this common RF-kill checking code into a common
function called by both transport generations and also moves it to
the direct method - in the internal helper we don't really care
about the RF-kill status anymore since we won't report it up until
the stop anyway.

When resuming, it's possible for the following scenario to occur:

 * iwl_pci_resume() enables the RF-kill interrupt
 * iwl_pci_resume() reads the RF-kill state (e.g. to 'radio enabled')
 * RF_KILL interrupt triggers, and iwl_pcie_irq_handler() reads the
   state, now 'radio disabled', and acquires the &trans_pcie->mutex.
 * iwl_pcie_irq_handler() further calls iwl_trans_pcie_rf_kill() to
   indicate to the higher layers that the radio is now disabled (and
   stops the device while at it)
 * iwl_pcie_irq_handler() drops the mutex
 * iwl_pci_resume() continues, acquires the mutex and calls the higher
   layers to indicate that the radio is enabled.

At this point, the device is stopped but the higher layers think it's
available, and can call deeply into the driver to try to enable it.
However, this will fail since the device is actually disabled.

The SPLC data parsing is too restrictive and was not trying find the
correct element for WiFi.  This causes problems with some BIOSes where
the SPLC method exists, but doesn't have a WiFi entry on the first
element of the list.  The domain type values are also incorrect
according to the specification.

Fix this by complying with the actual specification.

Additionally, replace all occurrences of SPLX to SPLC, since SPLX is
only a structure internal to the ACPI tables, and may not even exist.
