The module needs an external firmware file.

The module has been tested on a Pinnacle 330e, but with modules that
are currently not part of the linux-dvb tree. So consider this highly
experimental, don't use this code unless you are an experienced kernel
developer.

When an error occurs at firmware loading, sometimes, tda1004x stops answering.
Instead of reporting such error, attach code were assuming that the device were
answering an invalid ID (0xff). This can be seen when enabling debug options:

tda1004x: tda1004x_read_byte: reg=0x0
tda1004x: tda1004x_read_byte: error reg=0x0, ret=-5

Now, instead of reporting an invalid ID, it will report the correct error:

tda10046: chip is not answering. Giving up.
saa7133[0]/dvb: failed to attach tda10046
saa7133[0]/dvb: frontend initialization failed

A possible improvement would be trying to reset the device.

A fresh copy of v.29 firmware, using get_firmware, is leading to an invalid
firmware:

DVB: registering new adapter (saa7133[0])
DVB: registering frontend 0 (Philips TDA10046H DVB-T)...
tda1004x: setting up plls for 48MHz sampling clock
tda1004x: found firmware revision ff -- invalid
tda1004x: trying to boot from eeprom
tda1004x: found firmware revision ff -- invalid
tda1004x: waiting for firmware upload...
tda1004x: Error during firmware upload
tda1004x: found firmware revision ff -- invalid
tda1004x: firmware upload failed

Sometimes, loading/unloading this firmware makes tda1004x to return an invalid
ID. However, there were no printk messages to help to identify what were the
cause for the error.

With this patch, it will now print:

Invalid tda1004x ID = 0xff. Can't proceed
saa7133[0]/dvb: failed to attach tda10046
saa7133[0]/dvb: frontend initialization failed

This patch does some small cleanup to mt312.
It changes kconfig description to also list the ZL10313.

It does change some strange symbol names to be consistent with
module name mt312 and naming of all other functions in there.

* vp310_mt312_attach -> mt312_attach

Since:
1) FW_LOADER is defined as:

config FW_LOADER
        tristate "Userspace firmware loading support"
        depends on HOTPLUG

2) several V4L/DVB driver just selects it;

3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER.

So, All drivers that select FW_LOADER should also depend on HOTPLUG.

An easier solution (for the end-user perspective) would be to "select HOTPLUG".
However, live is not simple. This would cause recursive dependency issues like
this one:

drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD
-> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA ->

they can support also analog TV. Better to move them to the same place
as the other hybrid tuners. This would make easier to use those tuners also
