net: stmmac: dwmac4: Allow platforms to specify some DMA/MTL offsets
[ Upstream commit 33719b57f52e5b761234373f98f55f4e036d61c9 ]
Some platforms have dwmac4 implementations that have a different
address space layout than the default, resulting in the need to define
their own DMA/MTL offsets.
Extend the functions to allow a platform driver to indicate what its
addresses are, overriding the defaults.
