[PATCH v1] hw/ssi/aspeed_smc: Fix incorrect FMC_WDT2 register read on AST1030

[Jamin Lin via <qemu-arm@nongnu.org>]

On AST1030, reading the FMC_WDT2 register always returns 0xFFFFFFFF.
This issue is due to the aspeed_smc_read function, which checks for the
ASPEED_SMC_FEATURE_WDT_CONTROL feature. Since AST1030 was missing this
feature flag, the read operation fails and returns -1.

To resolve this, add the WDT_CONTROL feature to AST1030's feature set
so that FMC_WDT2 can be correctly accessed by firmware.
