As previously reported, some userspace applications depend on bogomips
showed by /proc/cpuinfo. Although there is much less legacy impact on
aarch64 than arm, it does break libvirt.
This patch reverts commit 326b16db9f ("arm64: delay: don't bother
reporting bogomips in /proc/cpuinfo"), but with some tweak due to
context change and without the pr_info().

As pointed by Laurent Navet:
"Calling ktime_add_us() seems useless as is only useful
for it's return value which is ignored."
That's reported by coverity CID 1309761.
Laurent proposed to just remove ktime_add_us, but the fact is that
the logic of this function is broken. Instead, we need to use the
value of the timeout, and ensure that it will work on the loops
to emulate the legacy DiSEqC ioctl (FE_DISHNETWORK_SEND_LEGACY_CMD).
Please notice that the logic was also broken if, for any reason,
msleep() would sleep a little less than what it was expected, as
newdelta would be smaller than delta, and udelay() would not be called.
It should also be noticed that nobody noticed that trouble before
likely because the FE_DISHNETWORK_SEND_LEGACY_CMD is not used
anymore by modern DVB applications.

When stopping the CSI2 receiver the s_stream handler will wait for the
IRQ handler to notice the stop request. The receiver, automatically
disabled by the hardware after each frame, is then not reenabled by the
IRQ handler as it returns immediately.
As the IRQ handler check is performed before handling the context IRQ,
the context IRQ source isn't cleared, and the CSI2 IRQ is then fired
again immediately. The IRQ handler then fails to notice that the module
is being stopped, processes the IRQ normally and reenables the CSI2
hardware.
The problem goes unnoticed at stream stop time, but depending on the IRQ
and s_stream scheduling timings, the CSI2 receiver can end up being
hanged and will not produce any interrupt the next time it gets enabled,
despite being soft-reset then.
Fix this by checking for module stop after clearing the context IRQ
source.

UVC 1.5 devices report a bInterfaceProtocol value set to 1 in their
interface descriptors. The uvcvideo driver only matches on
bInterfaceProtocol 0, preventing those devices from being detected.
More changes to the driver are needed for full UVC 1.5 compatibility.
However, at least the UVC 1.5 Microsoft Surface Pro 3 cameras have been
reported to work out of the box with the driver with an updated match
table.
Enable UVC 1.5 support in the match table to support the devices that
can work with the current driver implementation. Devices that can't will
fail, but that's hardly a regression as they're currently not detected
at all anyway.
