If APU firmware file read failed, the jump vector to the APU was undefined and
the APU would be started executing garbage. Fix uninitialized variable to be
an infinite loop for the APU, but also bail out before even starting the APU.

When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it
also received that interrupt and cleared the flag before the linux driver could
see what the interrupt was for. This fix prevents the CPU from receiving an
IRQ for it's own outgoing ack's to the linux driver. This fix is critical now
that the linux driver doesn't poll but relies on these ack interrupts.

Use the APU fw start address from rom file instead of a hardcoded entry vector.
Fixed cx18_setup_page() calls to use the correct APU image load addresses.

cx18: Fix write retries for registers that always change - part 3.
Fix the io for the rest of the registers that will often not read back the
value just written. Modified register readback checks to make sure the
intended effect was achieved without constantly rewriting the registers.
The one outstanding register remaining is 0xc72014 CX18_AUDIO_ENABLE, whose
behavior on writes I have yet to determine.

cx18: Create cx18_ specific wrappers for all pci mmio accessesors. This is a
first step in instrumenting all CX23418 PCI bus IO, to debug problems with
accessing the CX23418's PCI memory mapped IO.

This check was an ivtv leftover that served no purpose for the cx18.
Removed it, as this allows the user to load different firmware versions.

Conexant graciously gave us permission to redistribute the
firmware. Update the documentation where the firmware can be
downloaded.

- add radio definition
- reset the audio firmware (required for this board, harmless for the
others)

Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from
Conexant for their support. I am in particular thankful to Hauppauge
since without their help this driver would not exist. It should also
be noted that Steve did the work to get the DVB part up and running.
Thank you!
