Tuner ID set into EEPROM is wrong, which causes driver to select
wrong tuner profile. That leads device non-working. Fix issue by
overriding known bad tuner IDs with suitable default value.

Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.

This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

Exporting functions for hardware filter is a bad idea, as it
breaks compilation if:
	CONFIG_DVB_USB_AF9035=y
	CONFIG_DVB_AF9033=m

Because the PID filter function calls would be hardcoded at
af9035.

The same doesn't happen with af9033_attach() because the
dvb_attach() doesn't hardcode it. Instead, it dynamically
links it at runtime.

However, calling dvb_attach() multiple times is problematic,
as it increments module kref.

So, the better is to pass one parameter for the af9033 module
to fill the hardware filters, and then use it inside af9035.

PID filters are property of af9033 demod. Use PID filters from af9033
driver as it provides those now.

Allow possible dual mode on USB 1.1 mode too as bandwidth could be
just enough when filters are used on both frontends.

USB_PID_ITETECH_IT9135 v1 & v2
USB_PID_ITETECH_IT9135_9005 v1
USB_PID_ITETECH_IT9135_9006 v2

Current Issues
There is no signal  on
USB_PID_ITETECH_IT9135 v2

No SNR reported all devices.

All single devices tune and scan fine.

All remotes tested okay.

Dual device failed to register second adapter
USB_PID_KWORLD_UB499_2T_T09
It is not clear what the problem is at the moment.

So only single IDs are transferred in this patch.

Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
	drivers/media/usb/dvb-usb-v2/af9035.c:142:1: warning: 'af9035_wr_regs' uses dynamic stack allocation [enabled by default]
	drivers/media/usb/dvb-usb-v2/af9035.c:305:1: warning: 'af9035_i2c_master_xfer' uses dynamic stack allocation [enabled by default]
Instead, let's enforce a limit for the buffer to be the max size of
a control URB payload data (64 bytes).
