hw/arm/aspeed: Do not create and attach empty SD cards by default
Since added in commit 2bea128c3d, each SDHCI is wired with a SD
card, using empty card when no block drive provided. This is not
the desired behavior. The SDHCI exposes a SD bus to plug cards
on, if no card available, it is fine to have an unplugged bus.
Avoid creating unnecessary SD card device when no block drive
provided.
Fixes: 2bea128c3d ("hw/sd/aspeed_sdhci: New device")
