Intel Lynx Point: Use 2 << 24 to clarify that I/O APIC ID is 2 

Commit »haswell: Add initial support for Haswell platforms« (76c3700f)
[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.
