The newly added and existing TSN functionality is dependent on conditional
kernel config options. The AXI Ethernet and TSN functionality cannot both
be supported with the same defconfig in the current state. Hence move
TSN to staging area and split the two drivers as temporary solution until
an acceptable upstream solution is possible.

-> Move TSN specific files to staging area and make a copy of the common
files (header, mcdma and main files).
-> Remove all TSN specific code present under both dynamic and static
checks in the Axi Ethernet driver. Remove tsn compatible string.
-> The default config cannot include CONFIG_AXIENET_HAS_MCDMA because
it affects the baseline AXI Ethernet driver. Hence modify TSN
staging driver to default to MCDMA specific code as required.
-> Remove CONFIG_XILINX_AXI_EMAC_HWTSTAMP specific code in staging
as it is not used in TSN driver.
-> Remove unused non-static functions and related exported symbols in
tsn staging driver.
-> In staging, rename all non-static functions and macros with a _tsn
suffix when affected by either the above changes or by CONFIG_XILINX_TSN
being enabled in defconfig. This ensures that driver/net/ethernet/xilinx
and drivers/staging/xilinx-tsn drivers do not have any conflicts.
-> Added ethtool support
-> Fixed irq handling in mcdma_rx_probe_tsn
