FSP is currently setting a hard-coded policy for the interrupt
polarity settings. When the mainboard has already set the GPIO
settings up prior to SiliconInit being called that results
in the previous settings being dropped. Work around FSP's

The interrupt and timer subsystem (ITSS) sits between the APIC
and the other logic blocks. It only supports positive polarity
events, but there's a polarity inversion setting for each IRQ such
that it can pass the signal on to the APIC according to the
expected APIC redirection entry values. This support is needed
in order for the platform/board to set the expected interrupt
polarity into the APIC for gpio signals.

Internally, apollolake routes its interrupts as active high.
This includes SCI, SMI, and ACPI. Therefore, provide helper
macros such that the user can describe an interrupt's active
high/low polarity more easily. It helps for readability when
one is comparing gpio configuration next to APIC configuration
in different files. Additionally, the gpio APIC macros always
use a LEVEL trigger in order to let the APIC handle the
filtering of the IRQ on its own end.

The P2SB device is device 0xd and function 0. If hidden that
causes the latter pci devices on function >= 1 to not be probed
in the kernel. This is also a problem for coreboot if the P2SB
device is hidden by FSP. That means the coreboot driver won't
be ran. Therefore, provide hide and unhide functions for the
P2SB device.
The other quirk is to allow the GPIO devices to work correctly.
Those devices are ACPI devices. However, their resources are
sub-regions within the P2SB BAR. Sadly, linux doesn't handle
ACPI devices being children of PCI devices. This leads to resource
conflict errors when the P2SB device is visible. For the
time being keep the P2SB device hidden, but also ensure the
resources it is using are accounted for and reserved. The fallout
of that is the PMC and SPI device are no longer probed by the
kernel.

Because the resource for the ACPI BAR is fixed, pci_dev_set_resources
does not store it to the device. This means we need to do part of the
dance to get the ACPI IO region to work after coreboot.
Of course, this BAR can be destroyed later by the OS probing it, but
at least we try to get it working out of coreboot.
