Implement write_acpi_table() to create a minimal working ACPI table.
This includes writing FACS, XSDT, RSDP, FADT, MCFG, MADT, DSDT & SSDT
ACPI table entries.
Use a Kconfig option GENERATE_ACPI_TABLE to tell U-Boot whether we need
actually write the APCI table just like we did for PIRQ routing, MP table
and SFI tables. With ACPI table existence, linux kernel gets control of
power management, thermal management, configuration management and
monitoring in hardware.

Per Intel FSP specification, we should call FSP notify API to
inform FSP that PCI enumeration has been done so that FSP will
do any necessary initialization as required by the chipset's
BIOS Writer's Guide (BWG).
Unfortunately we have to put this call here as with driver model,
the enumeration is all done on a lazy basis as needed, so until
something is touched on PCI it won't happen.
Note we only call this after U-Boot is relocated and root bus has
finished probing.

With dm pci conversion, pci config read/write in unprotect_spi_flash()
silently fails as at that time dm pci is not ready and bus enumeration
is not done yet. Actually we don't need to do this in that early phase,
hence we delay this call to arch_misc_init().

On some platforms pci devices behind bridge need to be probed (eg:
a pci uart on recent x86 chipset) before relocation. But we won't
bind all devices found during the enumeration. Only devices whose
driver with DM_FLAG_PRE_RELOC set will be bound. Any other generic
devices except bridges won't be bound.

When ifdtool collates the microcode into one place it effectively creates
a copy of the 'data' properties in the device tree microcode nodes. This
is wasteful since we now have two copies of the microcode in the ROM.
To avoid this, remove the microcode data from the device tree and shrink it
down. This means that there is only one copy and the overall ROM space used
by the microcode does not increase.

The Intel Firmware Support Package (FSP) requires that microcode be provided
very early before the device tree can be scanned. We already support adding
a pointer to the microcode data in a place where early init code can access.
However this just points into the device tree and can only point to a single
lot of microcode. For boards which may have different CPU types we must
support multiple microcodes and pass all of them to the FSP in one place.
Enhance ifdtool to scan all the microcode, place it together in the ROM and
update the microcode pointer to point there. This allows us to pass multiple
microcode blocks to the FSP using its existing API.
Enable the flag in the Makefile so that this feature is used by default for
all boards.

Intel FSP has the capability to walk through the microcode blocks
which are passed as the TempRamInit() parameter from U-Boot and
finds the most appropriate microcode which is suitable for the cpu
on which it is running. Now we've seen several steppings for Intel
BayTrail series processors, adding those microcodes to the Intel
BayleyBay and MinnowMax board device tree files.

This patch moves pxa to the common timer functions added in commit
8dfafdd - Introduce common timer functions <Rob Herring>
The (removed) pxa timer code (specifically __udelay()) could deadlock at
the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value
cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed
the 32-bit boundary, the while condition became unconditionally true and
locked the processor. Rather than patch the specific pxa issues, simply
move everything over to the common code.

Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors")
pxa does not boot anymore.
Add a specific relocate_vectors macro that skips the vector relocation,
as the pxa SoC does not provide RAM at the high vectors address
(0xFFFF0000), and (0x00000000) maps to ROM.
This allows pxa to boot again.
