arm64: zynqmp: Define default SPL_TEXT_BASE address in Kconfig

Define default address via Kconfig. There is no need to change this address
for most of the boards but it is also possible. This one line save a lot of
lines in defconfigs that's why make sense to do it.

The similar change has been done by commit 9340d8fe8beb

NET: DW: fix regression for ARC boards

The commit
642b80d256e ("net: designware: drop compatible altr, socfpga-stmmac")
breaks designware ethernet for all ARC boards. It removes
"altr, socfpga-stmmac" compatible from "drivers/net/designware.c"
without changing compatible in the boards which use it.

Fix that by adding "snps,arc-dwmac-3.70a" compatible string to
"drivers/net/designware.c" and using it in ARC boards device tree.
