[PATCH 3/4] ARM: dts: aspeed: ast2600-evb: Adjust SPI flash configuration

- Enable FMC CS1 and SPI2 CS0 SPI NOR flashes since both of
  these two flashes are mounted on AST2600 EVB by default.
- Remove spi-max-frequency setting: 50MHz is usual SPI bus
  frequency adopted on AST2600 EVB which has already been
  configured in aspeed-g6.dtsi.
