9ae44aeada vmm: acpi_tables: Fix PM timer I/O port width
Ensure that the width of the I/O port is correctly set to 32-bits in the
generic address used for the X_PM_TMR_BLK. Do this by type
parameterising GenericAddress::io_port_address() fuction.

TEST=Boot with clocksource=acpi_pm and observe no errors in the dmesg.

Fixes: #1496
