ahci: don't enable port irq before handler is registered
commit 7b3a24c57d2eeda8dba9c205342b12689c4679f9 upstream.
The ahci_pmp_attach() & ahci_pmp_detach() unmask port irqs, but they
are also called during port initialization, before ahci host irq
handler is registered. On ce4100 platform, this sometimes triggers
"irq 4: nobody cared" message when loading driver.
Fixed this by not touching the register if the port is in frozen
state, and mark all uninitialized port as frozen.
