When a PCI bridge is not enabled, the secondary bus may still be zero.
This causes an infinite recursive call to enumerate bus 0 which results
in a stack overflow. The easy fix is to skip the recursive bus
enumeration for bridges which do not have the secondary bus initialized.

UEFI 2.6 spec has minor update to the Data parameter for GetVariable(),
and no real functional behavior change.
The modifier of Data parameter:
OUT VOID *Data
->
OUT VOID *Data OPTIONAL
The comments of Data parameter:
Data The buffer to return the contents of the variable.
->
Data The buffer to return the contents of the variable. May be NULL
with a zero DataSize in order to determine the size buffer needed.
The patch is to follow the spec to update the implementation.

When looping through all PCI functions, code should not look for functions
1-7 if function 0 is not present or if function 0 indicates the device is
not multifunction. Prior to this fix the code would use stale data in a
buffer to determine if a device is multifunction even if function 0 is not
present. This fixes a code bug and provides very small performance
improvements.
PCI 2.3 Specification states: They [multifunction devices] are also
required to always implement function 0 in the device. Implementing other
functions is optional and may be assigned in any order.

Each one of the DisqualifiedModes, IdentifyData and IdentifyValid arrays
in the EFI_SATA_CONTROLLER_PRIVATE_DATA structure is a matrix, represented
as a flat array.
The code currently uses the incorrect formula
Channel * Device
to index them. The right formula is
[Channel][Device]
which can be implemented as
Channel * NumDevicePerChannel + Device
Add a helper function that does this, and replace the incorrect
subscripts.

We strongly prefer that contribtions be offered using the same license
as the project/module. But, we should document other acceptable
licenses for contributions.
This will allow package owners to more easily know if they can accept
a contribution under a different source license.
