Parshuram Thombare 95b00f6820 PCI: cadence: Clear FLR in device capabilities register 
Clear FLR (Function Level Reset) from device capabilities
registers for all physical functions.

During FLR, the Margining Lane Status and Margining Lane Control
registers should not be reset, as per PCIe specification.
However, the controller incorrectly resets these registers upon FLR.
This causes PCISIG compliance FLR test to fail. Hence preventing
all functions from advertising FLR support if flag quirk_disable_flr
is set.
