acpi: Move some errors with RSDP and XSLT out from under bootverbose

Failure to map RSDP, XSLT and checksum failures are events that can't
happen unless something has gone wrong. As such, they should be reported
always, and not in bootverbose. This has been this way since it was
originally brought in to parse APIC tables.

Use pmap_mapbios() to map ACPI tables on amd64 and i386.

The ACPI table-mapping code used pmap_kenter_temporary() to create
mappings, which in turn uses the fixed-size crashdump map. Moreover,
the code was not verifying that the table fits in this map, so when
mapping large tables we could clobber adjacent mappings. This use of
pmap_kenter_temporary() appears to predate support in pmap_mapbios() for
creating early mappings, but that restriction no longer applies.

sys/amd64: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

If x86 CPU implementation of the MWAIT instruction reasonably
interacts with interrupts, query ACPI and use MWAIT for entrance into
Cx sleep states. Support C1 "I/O then halt" mode. See Intel'
document 302223-007 "Intelб╝ Processor Vendor-Specific ACPI Interface
Specification" for description.

Move the acpi_cpu_c1() function into x86/cpu_machdep.c and use
it instead of inlining "sti; hlt" sequence in several places.

In the acpi(4) man page, besides documenting the dev.cpu.N.cx_methods
sysctl, correct the names for dev.cpu.N.{cx_usage,cx_lowest,cx_supported}
sysctls.

Both jkim and avg have some other patches implementing the mwait
functionality; this work is unrelated. Linux does not rely on the
ACPI to provide correct tables describing Cx modes. Instead, the
driver has pre-defined knowledge of the CPU models, it was supplied by
Intel.
