On Arm platforms that use ACPI they cannot rely on the "spin-table"
CPU bringup usually defined in the FDT. Thus implement the
'ACPI Multi-processor Startup for ARM Platforms', also referred to as
'ACPI parking protocol'.
The ACPI parking protocol works similar to the spin-table mechanism, but
the specification also covers lots of shortcomings of the spin-table
implementations.
Every CPU defined in the ACPI MADT table has it's own 4K page where the
spinloop code and the OS mailbox resides. When selected the U-Boot board
code must make sure that the secondary CPUs enter u-boot after relocation
as well, so that they can enter the spinloop code residing in the ACPI
parking protocol pages.
The OS will then write to the mailbox and generate an IPI to release the
CPUs from the spinloop code.
For now it's only implemented on ARMv8, but can easily be extended to
other platforms, like ARMv7.

Add a new method to write the processor device identified by _HID

The fields Creator ID and Creator Revision contain information about the
tool that created an ACPI table. This may be the ASL compiler for some
tables but it is not for others. Naming these fields aslc_id and
aslc_revision is misleading.
It is usual to see diverse values of Creator ID. On a laptop I saw these:
'AMD ', 'INTL, 'MSFT', 'PTEC'. Obviously not all relate to the Intel
ASL compiler.

At present acpi_setup_base_tables() both sets up the ACPI context and
writes out the base tables.
We want to use an ACPI writer to write the base tables, so split this

acpi_setup_base_tables() just doing the base tables.
Disable the writer's write_acpi_tables() function for now, to avoid

At present all tables are placed starting at address f0000 in memory, and
can be up to 64KB in size. If the tables are very large, this may not
provide enough space.
Also if the tables point to other tables (such as console log or a ramoops
area) then we must allocate other memory anyway.
The bloblist is a nice place to put these tables since it is contiguous,
which makes it easy to reserve this memory for linux using the 820 tables.
Add an option to put some of the tables in the bloblist. For SMBIOS and
ACPI, create suitable pointers from the f0000 region to the new location
of the tables.
