[PATCH v2] board: sophgo: milkv_duo_256m: fix fdtfile quoting

[Hiago De Franco]

CONFIG_DEFAULT_DEVICE_TREE is a quoted string, so the quotes end up in
the environment:

  fdtfile="sg2002-milkv-duo256m".dtb

Use DEFAULT_DEVICE_TREE instead, which the build passes to the
environment preprocessor without the quotes:

  fdtfile=sophgo/sg2002-milkv-duo256m.dtb

Fixes: 98b59e181daa ("board: sophgo: add support for Milk-V Duo 256M")

https://lore.kernel.org/all/20260930-256m-fixes-v1-0-69546876ff28@baylibre.com/,
as asked by Yao Zi.

Tested on the Milk-V Duo 256M (SG2002).
---
Changes in v2:
- Drop "riscv: cpu: cv1800b: keep U-Boot out of reserved memory". The
  coprocessor reserved-memory nodes are being dropped from the upstream
  Milk-V Duo devicetrees, which makes the workaround unnecessary.
- Link to v1: https://lore.kernel.org/all/20260930-256m-fixes-v1-0-69546876ff28@baylibre.com/
