Declare jedec,spi-nor flash nodes with the properties previously
inherited from aspeed-g6.dtsi stubs. Keep status = "okay" so these
boards stay enabled while the SoC stubs still exist.

SPI NOR flashes describe board population, not SoC IP. With boards
now declaring the flashes they use, drop the disabled flash@*
stubs from aspeed-g6.dtsi and leave only the FMC/SPI controllers.
