USB: remove unused usb_buffer_alloc and usb_buffer_free macros
Now that all callers are converted over, remove the compatibility
functions and all is good.
As the function got renamed, the rename should also be applied at
tm6000.

The values for the fourcc format were correct, but applied to the
wrong register. With this change, video is now barely working again with
tm6000.
While here, let's remove, for now, the memset. This way, people can
have some image when testing this device.
Yet to be fixed: parts of the image frame are missed. As we don't clean
the buffers anymore, this is "recovered" by repeating the values from a
previous frame. The quality is bad, since the image pixels will contain
data from some previous frames, generating weird delay artifacts.

Changing a video standard takes a long time to happen on tm6000, since it
needs to load another firmware, and the i2c implementation on this device
is really slow. When the driver tries to change the video standard, a
kernel panic is produced:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
IP: [<ffffffffa0c7b48a>] tm6000_irq_callback+0x57f/0xac2 [tm6000]
...
Kernel panic - not syncing: Fatal exception in interrupt
By inspecting it with gdb:
(gdb) list *tm6000_irq_callback+0x57f
0x348a is in tm6000_irq_callback (drivers/staging/tm6000/tm6000-video.c:202).
197 /* FIXME: move to tm6000-isoc */
198 static int last_line = -2, start_line = -2, last_field = -2;
199
200 /* FIXME: this is the hardcoded window size
201 */
202 unsigned int linewidth = (*buf)->vb.width << 1;
203
204 if (!dev->isoc_ctl.cmd) {
205 c = (header >> 24) & 0xff;
206
Clearly, it was the trial to access *buf, at line 202 that caused the
Panic.
As ioctl is serialized, While S_STD is handled,QBUF/DQBUF won't be called.
So, the driver will run out of the buffers, and *buf will become NULL.
As, on tm6000, the same URB can contain more than one video buffer, it is
likely to hit a condition where no new buffer is available whily copying
the streams. The fix is to leave the URB copy loop, if there's no more buffers
are available.
The same bug could also be produced by an application that is not fast enough
to request new video buffers.
The same bug were reported by Bee Hock Goh <beehock@gmail.com>.

Yet another naming replace magic thanks to perl scripts. This time, it
is done with:

After looking at the "magic" registers, it is clear that usb registers
belong to request 5.
Replace them with this script:

$name=$2; $val=$3; printf "s,$1$2,TM6010_REQ05_R%s_%s,g\n", $val, $name; }' >a;

Instead of using magic pairs of req/reg, replace them by the defined

Use a pair Req/Reg for all registers at req07 and req08 groups. This
makes easier to replace them at the code with a script and helps to
avoid using the wrong req with some register.
This change were generated by this script:
if (m/^(\#define TM6010_REQ)([0-9].)([^\s]+)(\s+)0x([A-F0-9].)/) {
$name="$1$2$3"; $sp=$4; $req=$2; $val=$5; $val=~tr/A-F/a-f/; printf
"$name%s0x%s, 0x%s\n", $sp, $req, $val; } else { print $_ }

According with the original patch that added the register names, those
are related to tm6010, so name it properly as such. Also, clearly
indicates when a register belongs to Request 0x08 and add its register
value at the name. This makes easier to double check if the proper
register is used along the driver.
This patch were made with the help of this simple perl script, applied
over the definitions of the last register groups:
if (m/define (TM6000_)([^\s]+)\s+0x([A-F0-9].)/) { $name=$2;
$val=$3; printf "s,$1$2,TM6010_REQ08_R%s_%s,g\n", $val, $name; }
And were manually adjusted to fix a few minor issues.
