fsl/deepsleep: avoid the DDR restore from being optimized out
Function dp_ddr_restore is to restore the first 128-byte space
of DDR. However those codes may be optimized out by compiler
since the destination address is at 0x0. In order to avoid
compiler optimization, we restore the space from high address,
which is not at 0x0, to low address.

simplified IVOR initialization a bit too much, failing to use the
post-relocation offset. This doesn't cause a problem with normal NOR
boot, in which both the pre-relocation and post-relocation addresses
are 64 KiB aligned. However, if TEXT_BASE is only 4 KiB aligned, such
as for NAND/SD/etc. boot on some targets, as well as the QEMU target,
the post-relocation address will not be the same in the lower 16 bits,
as reserve_uboot() ensures that the relocation address is always 64

By default the legacy segments (A0000h-B0000h, E0000h-F0000h)
do not decode to system RAM. Turn on the decode so that we can
write configuration tables in the F segment.

x86: Check PIRQ routing table sanity in the F segment
Previously the PIRQ routing table sanity check was performed against
the original table provided by the platform codes. Now we switch to
check its sanity on the final table in the F segment as this one is
the one seen by the OS.

x86: Support platform PIRQ routing
On x86 boards, platform chipset receives up to four different
interrupt signals from PCI devices (INTA/B/C/D), which in turn
will be routed to chipset internal PIRQ lines then routed to
8259 PIC finally if configuring the whole system to work under
the so-called PIC mode (in contrast to symmetric IO mode which
uses IOAPIC).
We add two major APIs to aid this, one for routing PIRQ and the
other one for generating a PIRQ routing table.

x86: Add a function to assign IRQ numbers to PCI device
Add a function to assign an IRQ number to PCI device's interrupt
line register in its configuration space, so that the PCI device
can have its interrupt working under PIC mode after OS boots up.

x86: Add alias for SPI node in the board dts
Since Intel ICH SPI driver has been converted to driver model, we need
add an alias for SPI node in the board dts files otherwise SPI flash
won't be detected due to 'invalid bus' error.
