ArmPkg/PlatformBootManagerLib: regenerate boot options on boot failure
One of the side effects of the recent changes to PlatformBootManagerLib
changes to avoid connecting all devices on every boot is that we no
longer default to network boot on a virgin boot, but end up in the
UiApp menu. At this point, the UiApp will instantiate the autogenerated
boot options that we used to rely on as before, but since we are already
sitting idle in the root UiApp menu at that point, it does break the
unattended boot case where devices are expected to attempt a network
boot on the very first power on.
Let's work around this by refreshing all boot options explicitly in
the UnableToBoot() handler, and rebooting the system if doing so
resulted in a change to the total number of configured boot options.
This way, we ultimately end up in the UiApp as before if no boot
options could be started, but only after all the autogenerated ones
have been attempted as well.

EmbeddedPkg/NonCoherentDmaLib: avoid dereferencing bogus buffer address
The bounce buffering code in NonCoherentDmaLib copies data into the
bounce buffer using CopyMem(), but passes Map->HostAddress as the
source of the copy before it has been assigned its correct value.
