sil24 0.20 didn't use to perform (what seems to be) port multiplier
initialization and controller reset 0.10 driver does. This makes some
sil24 controllers malfunction. This patch adds PM initialization and
controller resetting to initilization and bumps version to 0.21.
Please refer to the following thread for more information.

03_sil24_add-pci-fault-check.patch
On entry to interrupt handler, PORT_SLOT_STAT register is read
first. Check if PCI fault or device removal has occurred by
testing the value for 0xffffffff.

02_sil24_remove-irq-disable-on-spurious-intr.patch
If interrupt occurs on a disabled port, the driver used to
mask the port's interrupt, but we don't know if such action is
necessary yet and that's not what other drives do. So, just
do nothing and tell IRQ subsystem that it's not our interrupt.
