Add the Audio DSP device for apollolake as a PCI driver with a static
scan_bus handler so generic devices can be declared under it.
This is for devices like the Maxim 98357A which is connected on the
I2S bus for data but has no control channel bus and instead just has
a GPIO for channel selection and power down control and needs to
describe that GPIO connection to the OS via ACPI.

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.
BUG=chrome-os-partner:53017
TEST=Ensured P2SB device is visible and pci resources are allocated
correctly for the devices.

There are four GPIO communities in this SOC and they are implemented
as separate ACPI devices. This means the pin number that is used in
an ACPI GPIO declaration needs to be relative to the community that
the pin resides in. Also select GENERIC_GPIO_LIB in the SOC Kconfig
so this function actually gets used.
This was tested on the reef mainboard by verifying the output of the
SSDT for the Maxim 98357A codec that the assigned GPIO_76 is listed
as pin 0x24 which is the value relative to the Northwest community.
