Add an override of read_status to intercept lock status. This allows
us to switch LEDs appropriately on and off with signal un/locked.
The second phase is to override sleep to properly turn off both.
This is a hackish way to achieve that.

To properly support the three LEDs which are on the stick, we need
a special handling in the ->frontend_attach function. Thus let's have
a separate ->frontend_attach instead of ifs in the common one.
The hadnling itself will be added in further patches.

If the frontend is in idle state, don't call get_frontend.
Calling get_frontend() when the device is not tuned may
result in wrong parameters to be returned to the
userspace.
I was tempted to not call get_frontend() at all, except
inside the dvb frontend thread, but this won't work for
all cases. The ISDB-T specs (ABNT NBR 15601 and ARIB
STD-B31) allow the broadcaster to dynamically change the
channel specs at runtime. That means that an ISDB-T optimized
application may want/need to monitor the TMCC tables, decoded
at the frontends via get_frontend call.
So, let's do the simpler change here.
Eventually, the logic could be changed to work only if
the device is tuned and has lock, but, even so, the
lock is also standard-dependent. For ISDB-T, the right
lock to wait is that the demod has TMCC lock. So, drivers
may need to implement some logic to detect if the get_frontend
info was retrieved or not.

This fixes bug introduced by multi-frontend to single-frontend change.
Finally HAS_LOCK is got back!
We are not allowed to access hardware in sleep mode...
Chip did not like when .get_frontend() reads some registers while
chip was sleeping and due to that HAS_LOCK bit was never gained.
TODO: We should add logic for dvb-core to drop out illegal calls like that.

The caller doesn't check the return value of check_firmware() but static
checkers complain. It currently returns negative error codes, or zero
or greater on success but since the return type is boolean the values
are truncated to one or zero. I've changed it to return an int,
negative on error and zero on success.

In xc4000 chipsets real signal and noise level is stored in register
0x0A and 0x0B,so we can use those registers to monitor signal strength.
I tested this patch on 2 different cards Leadtek DVR3200 and DTV2000H
Plus, both with same results, I used special antenna hubs (toner 4x, 6x,
8x and 12x) with mesured signal lost, both registers are in dB value,
first represent signal with limit value -113.5dB (should be -114dB) and
exactly match with test results. Second represents noise level also in
dB and there is no maximum value, but from tests we can drop everything
above 32dB which tuner realy can't use, signal was usable till 20dB
noise level.
In digital mode we can take signal strength but sadly noise level is not
relevant and real value is stored in demodulator for now just zl10353,
also digital mode is just for testing, because it needs changing other
parts of code which reads data only from demodulator.
In analog mode I was able to test only FM radio, signal level is not
important, it says something about cable and hub losts, but nothing
about real quality of reception, so even if we have signal level at
minimum 113dB we can still here radio, because of that it is displaied
only in debug mode, but for real signal level is used noise register
which is again very accurate, radio noise level was betwen 6-20dB for
good signal, 20-25dB for medium signal, and above 25dB signal is
unusable.
For now real benefit of this patch is only for FM radio mode.

The pwc driver used to:
1. kmalloc a buffer
2. memcpy data to send over usb there
3. do the usb_control_msg call (which does not work with data on the stack)
4. free the buffer
For every usb command send. This patch changes the code to instead malloc
a buffer for this purpose once and use it everywhere.
