Intel 82801gx: Use 2 << 24 to clarify that I/O APIC ID is 2
Commit »Support for the Intel ICH7 southbridge.« (debb11fc) [1] used
`1 << 25` to set the I/O APIC ID of 2. Instead using `2 << 24`, which
is the same value, makes it clear, that the I/O APIC ID is 2.
Commit »Intel Panther Point PCH: Use 2 << 24 to clarify that APIC ID
is 2« (8c937c7e) [2] is used as a template.
