[PATCH v5 07/18] hw/usb/hcd-ehci: Introduce common properties macro for sysbus and pci

[Jamin Lin <jamin_lin@aspeedtech.com>]

EHCI properties are currently defined separately in both sysbus and
PCI implementations, leading to duplicated code for common fields
such as "maxframes".

Introduce DEFINE_EHCI_COMMON_PROPERTIES() to consolidate shared
property definitions and reuse them across both EHCISysBusState
and EHCIPCIState.

This reduces code duplication and keeps property definitions
consistent between different EHCI device variants.

No functional change.
