For now, the m5mols_read() share in case of I2C packet 1, 2, 4 byte(s) width.
So, this commit adds 3 functions - m5mols_read_u8/u16/u32() according to byte
width of I2C packet. And, the u32 variables in spite of u8 or u16 for fitting
to m5mols_read() having no choice, is replaced to have original byte width
like u8, u16, u32 as same reason.

The main capture and the thumbnail image size registers were

Hans Petter Selasky pointed out to me that we're leaking urbs when
mce_async_out is called. Its used both for configuring the hardware and
for transmitting IR data. In the tx case, mce_request_packet actually
allocates both a urb and the transfer buffer, neither of which was being
torn down. Do that in the tx callback.

Store the cdev pointer in struct irctl, allocated dynamically as needed,
rather than having a static array. At the same time, recycle some of the
saved memory to nudge the maximum number of lirc devices supported up a
ways -- its not that uncommon these days, now that we have the rc-core
lirc bridge driver, to see a system with at least 4 raw IR receivers.
(consider a mythtv backend with several video capture devices and the
possible need for IR transmit hardware).

Aside from the initial "hey, lets make sure we've flushed any
pre-existing data on the device" call to mce_sync_in, every other one of
the calls was entirely superfluous. Ergo, remove them all, and rename
the one and only (questionably) useful one to reflect what it really
does. Verified on both gen2 and gen3 hardware to make zero difference.
Well, except that you no longer get a bunch of urb submit failures from
the unneeded mce_sync_in calls. Oh. And move that flush to a point
*after* we've wired up the inbound urb, or it won't do squat. I have
half a mind to just remove it entirely, but someone thought it was
necessary at some point, and it doesn't seem to hurt, so lets leave it
for the time being.

This excercise took place due to insightful questions asked by Hans
Petter Selasky, about the possible reuse of the inbound urb before it
was actually availble by mce_sync_in, so thanks to him for motivating
this cleanup.

The find_next_zero_bit() is called with the from and to arguments in the
wrong order. This results in the function always returning 0, and all
media devices being registered with minor 0. Furthermore, mdev->minor is
then used before being assigned with the find_next_zero_bit() return
value. This really makes sure we'll always use minor 0.

Fix this and let the system support more than one media device.
