This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

The FSP-S changes the ITSS priorities. The code that tries to save it
before running FSP-S and restore it afterwards does not work as U-Boot
relocates in between the save and restore. This means that the driver
data saved before relocation is lost and the new driver just sees zeroes.
Fix this by allocating space in the relocated memory for the ITSS data.
Save it there and access it from the driver after relocation.
This fixes interrupt handling on coral.
Also drop the log_msg_ret() in irq_first_device_type() since this function
can be called speculatively in places where we are not sure if there is
an interrupt controller of that type. The resulting log errors are
confusing when there is no error.

With P2SB the initial BAR (base-address register) is set up by TPL and
this is used unchanged right through U-Boot.
At present the reading of this address is split between the ofdata() and
probe() methods. There are a few problems that are unique to the p2sb.
One is that its children need to call pcr_read32(), etc. which needs to
have the p2sb address correct. Also some of its children are pinctrl
devices and pinctrl is used when any device is probed. So p2sb really
needs to get its base address set up in ofdata_to_platdata(), before it is
probed.
Another point is that reading the p2sb BAR will not work if the p2sb is
hidden. The FSP-S seems to hide it, presumably to avoid confusing PCI
enumeration.
Reading ofdata in ofdata_to_platdata() is the correct place anyway, so
this is easy to fix.
Move the code into one place and use the early-regs property in all cases
for simplicity and to avoid needing to probe any PCI devices just to read
the BAR.

Most x86 CPUs use a mechanism where the SPI flash is mapped into the very
top of 32-bit address space, so that it can be executed in place and read
simply by copying from memory. For an 8MB ROM the mapping starts at
0xff800000.
However some recent Intel CPUs do not use a simple 1:1 memory map. Instead
the map starts at a different address and not all of the SPI flash is
accessible through the map. This 'Fast SPI' feature requires that U-Boot
check the location of the map. It is also possible (optionally) to read
from the SPI flash using a driver.
Add support for booting from Fast SPI. The memory-mapped version is used
by both TPL and SPL on Apollo Lake.
In respect of a SPI flash driver, the actual SPI driver is ich.c - this
just adds a few helper functions and definitions.
This is used by Apollo Lake.
