[PATCH v2] hw/i386/acpi-build: Remove build-time assertion on PIIX/ICH9 reset registers being identical

[Bernhard Beschow]

Commit 6103451aeb74 ("hw/i386: Build-time assertion on pc/q35 reset register
being identical.") introduced a build-time check where the addresses of the
reset registers are expected to be equal. Back then rev3 of the FADT was used
which required the reset register to be populated and there was common code.
In commit 3a3fcc75f92a ("pc: acpi: force FADT rev1 for 440fx based machine
types") the FADT was downgraded to rev1 for PIIX where the reset register isn't
available. Thus, there is no need for the assertion any longer, so remove it.
