The firmware_has_feature() function makes it easy to check for supported features of the hypervisor. This patch extends the capability of firmware_has_feature() to include checking for specified bits in vector 5 of the architecture vector as reported in the device tree. As part of this the #defines used for the architecture vector are re-defined such that each option has the index into vector 5 and the feature bit encoded into it. This makes checking for architecture bits when initiating data for firmware_has_feature much easier.
