linux: Add stable version 4.7.3, select CPU_FREQ

Do as Greg says [1]:

> All users of the 4.7 kernel series must upgrade.

Summary of changes [2][3]:

> ### AMDGPU, Intel i915, and Btrfs improvements, many updated drivers ###
>
> Looking at the changelog, we can notice that Linux kernel 4.7.3 comes
> with several improvements to the Btrfs file system, many updated
> drivers, in particular for things like AMDGPU, Intel i915, hwmon, I2C,
> iiO, IOMMU, MD, PCI, PINCTRL, s390, USB, SCSI, VFIO, Virtio, GPIO,
> EDAC, DAX, DMA, ACPI, CLK, and Crypto, as well as some enhancements to
> the ARC, ARM64 (AArch64), PA-RISC, and x86 hardware architectures.
>
> Last but not least, the networking and sound stacks have been improved
> as well, with support for new sound devices, as well as various
> changes to the mac80211 wireless framework and SunRPC protocol. If
> you're using a GNU/Linux distribution powered by a kernel from the
> Linux 4.7 series, we recommend that you update to Linux kernel 4.7.3
> as soon as possible.  The sources are available for download right now
> via our website or from kernel.org.

Also, enable frequency scaling.
