PCI: endpoint: Drop only_64bit on reserved BARs
The definition of a reserved BAR is that EPF drivers should not touch
them.
The definition of only_64bit is that the EPF driver must configure this
BAR as 64-bit. (An EPF driver is not allowed to choose if this BAR should
be configured as 32-bit or 64-bit.)
Thus, it does not make sense to put only_64bit of a BAR that EPF drivers
are not allow to touch.
Drop the only_64bit property from hardware descriptions that are of type
reserved BAR.
