The grub-install mechanism for grub-efi requires efibootmgr
at runtime so add a dependency accordingly.

This enables git based grub recipes to be used
for AMD BSPs.

This actually copies over the grub-efi_2.00 recipe
and makes simple modifications so it can use git as
source. This will give us the chance to use the
latest and greatest grub/grub-efi on our platforms.

Rather than erroring out on a single attempt while
terminating EFI services, make a few retries because
such quirks are found in a few implementations.
Also fix a div by zero issue in the same framework
which causes an infinite reboot on the target.
Both patches included here are backports.

Unity3d apps need this to work. As per my investigation, there were previously
the following issues with pulseaudio.
1. It would reset values for the controls across reboots
2. A toggle cycle for master control would turn the sound off
3. Mute state for mic or headphones were not saved across reboots
All of these issues are not reproducible as per my testing. One thing to
note is that the master volume is retained only when set with default pcm
device (pulseaudio); all the other controls for the card, e.g. headphone,
mic etc can be set by selecting the right card in alsamixer.

Set the alsa card defaults to something other than '1' or '0' to
avoid naming conflicts during load or unload. After the recent
kernel update to 4.1.15, the ALC662 registers as 'Generic'.

Generic naming is used to address default device for alsa/audio.
This helps in a manner that adding/removing devices from the
system would not affect.

Card 1 is the default device on current AMD platforms. So
we update asound.conf to reflect this and make the card 1
the default device for ctl nodes as default. This allows
alsamixer to open the interface directly on this card by
default.

An issue was found where when yocto is installed to a hard disk
from a live USB key, no matter what boot order was selected in
the BIOS menu, the grub menu of the USB key would always show
up. The issue was narrowed down to the way grub configuration
file gets embedded into the standalone bootx64.efi image.
The commit prepends ($cmdpath) to the search path for grub.cfg,
thus making sure the UEFI environment itself sets this to the
correct device path. This in-turn lets the grub.cfg of the boot
device to be loaded.

This uses a combination of the asym, dmix and dsnoop plugins to
allow concurrent access to the alsa device using the Default
device. Primarily this is a convenience as it is a lowest
common denominator but it makes things mostly "just work"
out of the box.

This allows a single variable override to apply to
all AMD platforms rather than needing individual settings
per board.

Without this we are getting CPU ERROR 6 on the board and no
Grub launch.
