lib/acpi: Extend the definition of the FADT table

This change add more fields in the APCI table FADT to allow for the
discovery of the PSCI conduit in arm64 systems. The definition for
FADT is similar to the one in include/acpi/actbl.h in Linux.

x86: Avoid references to fields of ACPI tables

ACPI table definitions in <acpi.h> have to be packed. However, once
we do that, direct references to members of the packed struct might
result in unaligned pointers and gcc complains about them. This change
modifies the code to avoid such references in preparation for making
the APCI table definitions packed.

lib: x86: Use portable format macros for uint32_t

Compilation of the files fails on ARCH=i386 with i686-elf gcc because
they use "%x" or "%d" format specifier that does not match the actual
size of uint32_t:

x86/s3.c: In function ‘main’:
x86/s3.c:53:35: error: format ‘%x’ expects argument of type ‘unsigned int’, but argument 2 has type ‘u32’ {aka ‘long unsigned int’}

| ~^ ~~~~~~~~~~~~~~~~~~
| | |
| | u32 {aka long unsigned int}
| unsigned int
| %lx

Use PRIx32 instead of "x" and PRId32 instead of "d" to take into account
u32_long case.

for backwards compatibility reasons).

Q35 resets the wakeup reasons at startup (it is a bug that i440FX

For the S3 test to work with the Q35 machine types, we have to
enable RTC wakeup manually.
