Please apply some optimization patches.

Kirill Smelkov (4):
[media] vivi: Optimize gen_text()
[media] vivi: vivi_dev-line
for simplifying the code. That's done because for
memcpy used for conditional assignment, gcc generates suboptimal code
with more indirections.
Fortunately, in C struct assignment is builtin and that's all we
need from pixeltype for font rendering.

The only sysfs attr implemented so far is companion from ehci-hub.c,
but in the next patch we are going to add another sysfs file, so prior
to that let's structure things and move already-in-there sysfs code to
separate file.

NOTE: for two streams with max_pkt_size=3072 (worst case) both time
allocation would be 60us+60us=120us which is 96% periodic bandwidth
leaving 4% for bulk and control. I think this should work too.
