The logic at em28xx_isoc_dvb_max_packetsize() sucks, at least for newer
the needed packet size. Yet, it is better than nothing.
Rewrite the code in order to change the default to 752 for em2884 and
newer chips and provide a better way to handle per-chipset specifics.
For em2874, the current default should be enough, as the only em2874
board is currently a 1-seg ISDB-T board, so, it needs only a limited
amount of bandwidth.

On platforms that have CONFIG_HZ set to 100, the power ramp time effectively
ends up being 10ms. However, on those that have a higher CONFIG_HZ, the time
ends up *actually* being 5ms, which doesn't allow enough time for the hardware
to be fully powered up before attempting to address it via i2c.
Change the constant to 10ms, which is long enough for the hardware to power
up, and won't really be anymore time than it was previously on platforms
with CONFIG_HZ being 100.
Credit goes to Mauro Carvalho Chehab and Gerd Hoffmann who previously
investigated this issue.
Tested with the Hauppauge USBLive 2, with which the problem was readily
reproducible after setting CONFIG_HZ to 1000.

Confirmed working by both myself and the user who reported the issue

The search for matching extension units fails to take account of the
current chain. In the case where you have two distinct video chains,
both containing an XU with the same GUID but different unit ids, you
will be unable to perform a mapping on the second chain because entity
on the first chain will always be found first
Fix this by only searching the current chain when performing a control
mapping. This is analogous to the search used by uvc_find_control(),
and is the correct behaviour.

The right fix is to change them to use the same logic, but,
