acpidump: fix lint errors

When lint runs on the code, it defines the preprocessor macro 'lint' to
be 1. Due to that, this name cannot be used as a regular identifier.

acpi.c(86): error: syntax error '1' [249]
acpi.c(1004): error: syntax error '1' [249]
acpi.c(2422): error: void function acpi_print_lpit cannot return value
[213]

The FreeBSD code doesn't need this name change since lint is specific to
NetBSD.

No functional change.

Consistently use ACPI_SIG_SSDT

MAsk -> Mask, spotted by rillig@

Add support for decoding Platform Communications Channel Tables ("PCCT").

acpidump: Do not print FACS if HW_REDUCED flag is set.

According to ACPI 6.3 spec, FACS is optional when HW_REDUCED is set. ACPICA
ignores the FACS completely when HW_REDUCED is set, so we need to follow
suit since it is not available through /dev/acpi as the table is not
installed.

Dump TPM2.

acpica 20190405 changed some internal macros; update code to match

Add missing newline.

acpi: add character device for accessing ACPI tables

The /dev/acpi character device gives an aperture into physical memory
that allows only read access to known ACPI tables: RSDP, XSDT/RSDT, and
the root tables. Adapt acpidump(8) to use this interface by default,
falling back to the old /dev/mem method if it is not available or if
ACPIDUMP_USE_DEVMEM=1 is set in the environment. The user visible benefit
of this change is that "options INSECURE" is no longer required to
dump ACPI tables.
