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

of that is the PMC and SPI device are no longer probed by the

Additionally it is now possible for a board to override the values
using devicetree.cb. If zero is passed in for SCL HCNT or LCNT then
the kernel will generate its own timing using the same forumla, but if
the SDA hold time value is zero the kernel will NOT generate a correct
