0f45a1b5e7 Kernel: Allow to reboot in ACPI via PCI or MMIO access
Also, we determine if ACPI reboot is supported by checking the FADT
flags' field.

bf55d83c1f ACPI: Reorganize the definitions file
More namespaces have been added to organize the declarations
in a more sensible way.
Also, a namespace StaticParsing has been added to allow early
access to ACPI tables.

ebe30ed11e ACPI: Adding definitions for HPET
Also, definitions were added for MADT entries, like IOAPIC and GSI
overriding information.

a246e9cd7e Use uintptr_t instead of u32 when storing pointers as integers
uintptr_t is 32-bit or 64-bit depending on the target platform.
This will help us write pointer size agnostic code so that when the day
comes that we want to do a 64-bit port, we'll be in better shape.

94ca55cefd Meta: Add license header to source files
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.

For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.

Going forward, all new source files should include a license header.

2da8aba48d Kernel: Change ACPI & DMI definitions a bit
Structures declarations changed __attribute__((__packed__))
to [[gnu::packed]] in ACPI & DMI definitions.
Also, declarations of array of pointers in ACPI RSDT/XSDT are correct
now. In addition to that, now we have a declaration of the ACPI MADT
table & the table entries.

1e1a6a57ed Kernel: Introduce the ACPI subsystem
ACPI subsystem includes 3 types of parsers that are created during
runtime, each one capable of parsing ACPI tables at different level.

ACPIParser is the most basic parser which is essentialy a parser that
can't parse anything useful, due to a user request to disable ACPI
support in a kernel boot parameter.

ACPIStaticParser is a derived class from ACPIParser, which is able to
parse only static data (e.g. FADT, HPET, MCFG and other tables), thus
making it not able to parse AML (ACPI Machine Language) nor to support
handling of hardware events and power management. This type of parser
can be created with a kernel boot parameter.

ACPIDynamicParser is a derived class from ACPIStaticParser, which
includes all the capabilities of the latter, but *should* implement an
AML interpretation, (by building the ACPI AML namespace) and handling
power & hardware events. Currently the methods to support AML
interpretation are not implemented.
This type of parser is created automatically during runtime if the user
didn't specify a boot parameter related to ACPI initialization.

Also, adding strncmp function definition in StdLib.h, to be able to use
it in ACPIStaticParser class.
