Compiling FreeBSD/i386 with modern GCC triggers warnings for various
places that convert 64-bit EFI_ADDRs to pointers and vice versa.
- Cast pointers to uintptr_t rather than to uint64_t when assigning
to a 64-bit integer.
- Cast 64-bit integers to uintptr_t before a cast to a pointer.

Note when we've found a 8250 PNP node. Only try to set hw.uart.console
if we see one (otherwise ignore serial hints). The 8250 is the only
one known to have I/O ports, so limit the guessing to when we've
positively seen one. And limit this to x86 since that's the only
platform where we have I/O ports. Otherwise, we'd set the serial port
to something crazy for the platform and fall off the cliff early in
boot.

For server machines, ComOut is set to the set of devices that the efi
console suppots. Parse it to see if we have serial, video or both.
Make that take precidence over the command line args. boot1.efi parses
them, but loader.efi doesn't. It's not clear where to read boot.conf
from, so we don't do that. The command line args can still be set via
efibootmgr, which is more inline with the UEFI boot manager to replace
that. These args are typically used only to set serial vs video and
the com speed line. We can infer that from ComOut, so do so.
Remember the com speed and hw.uart.console to match.

This moves the bulk of the geli support from lib386/biosdisk.c into a new
geli/gelidev.c which implements a devsw-type device whose dv_strategy()
function handles geli decryption. Support for all arches comes from moving
the taste-and-attach code to the devopen() function in libsa.
After opening any DEVT_DISK device, devopen() calls the new function
geli_probe_and_attach(), which will "attach" the geli code to the open_file
struct by creating a geli_devdesc instance to replace the disk_devdesc
instance in the open_file. That routes all IO for the device through the
geli code.
A new public geli_add_key() function is added, to allow arch/vendor-specific
code to add keys obtained from custom hardware or other sources.
With these changes, geli support will be compiled into all variations of
loader(8) on all arches because the default is WITH_LOADER_GELI.

e.g. boot_mute, boot_single, boot_verbose, and friends; we checked for these
in multiple places, consolidate into common/ and allow a setting of "NO" for
any of these to turn them off. This allows systems with multiple
loader.conf(5) or loader.conf(5) overlay systems to easily turn off
variables in later processed files by setting it to NO.

This fixes a problem encountered on the Lenovo Thinkpad X220/Yoga 11e where
runtime services would try to inexplicably jump to other parts of memory
where it shouldn't be when attempting to enumerate EFI vars, causing a
panic.
The virtual mapping is enabled by default and can be disabled by setting
efi_disable_vmap in loader.conf(5).
