f6257f7914 x86: Move priv/plat structs for intel_common to headers
With the new of-platdata, these need to be available to dt_platdata.c
so must be in header files. Move them.

8b842be10c x86: apl: Reduce size for TPL
Update various drivers to use of_match_ptr() and to avoid including debug
strings in TPL. Omit the WiFi driver entirely, since it is not used in
TPL.

This reduces the TPL binary size by about 608 bytes.

b012ff1f1b dm: treewide: Update 'auto' declarations to be on one line
Fix up the code style for those declarations that should now fit onto one
line, which is all of them that currently do not.

This is needed for dtoc to detect the structs correctly, at present.

d1998a9fde dm: treewide: Rename ofdata_to_platdata() to of_to_plat()
This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
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.

9d20db0483 x86: Fix up driver names to avoid dtoc warnings
At present there are a lot of dtoc warnings reported when building
chromebook_coral, of the form:

   WARNING: the driver intel_apl_lpc was not found in the driver list

Correct these by using driver names that matches their compatible string.

1630853085 x86: apl: Move p2sb ofdata reading to the correct method
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.

5a9d7f9c91 x86: p2sb: Drop 'apl' prefix
Drop the Apollo Lake prefix 'apl' from the functions, types and
variables in the P2SB driver.

The P2SB is not Apollo Lake specific, and as such it was moved in
commit 2999846c11 ("x86: Move P2SB from Apollo Lake to a more generic
location") from the Apollo Lake folder to the intel_common folder.
