Pass in 'true' if you'd like to search this device's partitions or
'false' if you should just search the device. EFI and (in the future)
kboot have discrete partitions that aren't accessed via the full disk

Change the first argument to zfs_parsedev() to be a pointer to a struct
devdesc *. This now gets filled in with a malloc'd structure that's
returned to the caller that the caller is repsonsible for freeing. Most
nplaces in the tree passed in a malloc'd pointer anyway, and this moves
knowledge of zfs_devdesc more firmly into the zfs.c code.

The console escape code standard (ECMA-48) specifies color #3 (escape

For historical reasons console color number 3 may be either yellow (most
consoles) or brown (VGA palette). The console escape code standard
uses "yellow", but teken color name constants appear to be based on the
VGA scheme and use TC_BROWN for color 3. Even so, the palette table
used 50,50,0 as the RGB percentage tuple, resulting in a dim yellow for
framebuffer consoles at the time teken was introduced.
Amusingly, in 19e2ce2d83 the comment on the palette entry was changed
from "brown" to "dark yellow" but the colour itself was changed from
a pure yellow to being somewhat brown.

GOP and UGA in efi_find_framebuffer(), also we can then
set up struct gen_fb in gfx_state from efifb and isolate efi fb data
processing into framebuffer.c.
This change does allow us to clean up efi_cons_init() and reduce
BS->LocateProtocol() calls.
A little downside is that we now need to translate gen_fb back to
efifb in bootinfo.c (for passing to kernel), and we need to add few
-I options to CFLAGS.

During devswitch probe, we pick boot pool based on boot disk, if the boot
disk happens to have multiple pools in freebsd-zfs partitions, the current
code does pick last pool from boot disk as boot pool. While there is no
way at that stage to test, the more logical approach would be to pick
first matching pool.
This patch is assuming we do pass pool guid pointer with guid value 0,
this will help us to determine, if the guid value is already set or not.
The general suggestion would be not to share disk between different pools.

This implementation doesn't have any major deviations from the other EFI
ports. I've copied the boilerplate from arm and arm64.
I've tested this with the following boot flows:
OpenSBI (M-mode) -> u-boot (S-mode) -> loader.efi -> FreeBSD
OpenSBI (M-mode) -> u-boot (S-mode) -> boot1.efi -> loader.efi -> FreeBSD
Due to the way that u-boot handles secondary CPUs, OpenSBI >= v0.7 is required,
as the HSM extension is needed to bring them up explicitly. Because of this,
using BBL as the SBI implementation will not be possible. Additionally, there
are a few recent u-boot changes that are required as well, all of which will be
present in the upcoming v2020.07 release.
