x86 I/O APIC: Make functions `io_apic_{read,write}()` public

Some LPC initialiation can save some lines of code when being able
    to use the functions `io_apic_read()` and `io_apic_write()`.

As these two functions are now public, remove them from the generic
    driver as otherwise we get a build errors like the following.
