CHANGELOG: Mention PVH boot mode

Firecracker now supports PVH boot as an alternative to "Linux" boot on the x86_64 architecture. This makes it possible for FreeBSD to boot, and also affects how Linux kernels compiled with the CONFIG_XEN_PVH=y option boot. Signed-off-by: Colin Percival <[email protected]>

   capability checks that Firecracker performs during boot. If any of

   restricted to 1.5.
+- Added support for PVH boot mode.  This is used when an x86 kernel provides
+  the appropriate ELF Note to indicate that PVH boot mode is supported.
+  Linux kernels compiled with CONFIG_XEN_PVH=y set this ELF Note, as do
+  FreeBSD kernels.
