Build failed in Jenkins: FreeBSD_HEAD-modules #397

See <https://jenkins.freebsd.org/jenkins/job/FreeBSD_HEAD-modules/397/changes>

Changes:

[cperciva] In cf_get_method, when we don't already know what clock speed the CPU is
running at, guess the nearest value instead of looking for a value within
25 MHz of the observed frequency.

Prior to this change, if a system booted with Intel Turbo Boost enabled,
the dev.cpu.0.freq sysctl is nonfunctional, since the ACPI-reported
frequency for Turbo Boost states does not match the actual clock frequency
(and thus no levels are within 25 MHz of the observed frequency) and the
current performance level is read before a new level is set.

MFC after:	3 days
Relnotes:	Bug fix in power management on CPUs with Intel Turbo Boost

[hselasky] Optimise host mode data roundtrip time. When BULK data is submitted to
the main processing queue, clear the NAK counter for any associated
BULK or CONTROL transfers and poll the endpoint(s) for 1 millisecond
at 125us rate interval, before going into slow, 10ms, NAK polling mode
again.  This has the effect that typical ping-ping protocols respond
quicker when initiated from the USB host.

MFC after:	2 weeks
