aspeed/smc: Only wire flash devices at reset
The Aspeed machines have many Static Memory Controllers (SMC), up to
8, which can only drive flash memory devices. Commit 27a2c66c92ec
("aspeed/smc: Wire CS lines at reset") tried to ease the definitions
of these devices by allowing flash devices from the command line to be
attached to a SSI bus. For that, the wiring of the CS lines of the
Aspeed SMC controller was moved at reset. Two assumptions are made
though, first that the device has a SSI_GPIO_CS GPIO line, which is
not always the case, and second that it is a flash device.
Correct this problem by ensuring that the devices attached to the bus
are of the correct flash type. This fixes a QEMU abort when devices
without a CS line, such as the max111x, are passed on the command
line.
While at it, export TYPE_M25P80 used in the Xilinx Versal Virtual
machine.
