e45d6bfd8a superio/ite: Add function to disable PME# output
A function to disable the PME# output was added. This is required to
set up the SuperIO on the "HP Pro 3500 Series" mb.

a7c96155b9 superio/ite: Add function to disable 3VSBSW# signal
The 3VSBSW# signal can now also be disabled again which is necessary to
power components down properly in SMM when entering S5. In such cases
the signal will be enabled only in the SMM S3 handler.

fb51661be1 superio/ite: Unify it8772f with common code
The it8772f is now configured by the much better common code that is
used for other chips in the family as well. This mainly concerns the EC,
the GPIO functionality was not moved to common as it currently lacks a
sane abstraction in any codebase.

The datasheets of the it8772e(f) and it8728f (for reference) were
studied and verified against the common code, adding exceptions where
needed.

a7a40a5b10 superio/ite/common/early_serial.c: ite_kill_watchdog: set timeout to 0
Set the watchdog timeout to 0 in ite_kill_watchdog, as in some ITE
models it is set to non-zero by default, activating the watchdog despite
us setting the control register to 0.

Based on:
- "ITE IT8786E-I Preliminary Specification V0.4.1 (For D Version)"
- Linux it87_wdt driver

6c5f47b50c superio/ite: delay PWRGD3 during resume
According to the IT8728F datasheet it is possible to add an extra delay
between 3VSBSW# being set and PWRGD3 being set during resume from
Suspend-to-RAM. This is enabled in the special function selection
register, the default being 0.

This is also useful for the IT8720F although this chip does not have the
PWRGD3 output. On the corresponding pin it has PWROK2, which the setting
then seems to apply to.

The datasheet for the IT8720F marks the corresponding bit as reserved,
but the vendor BIOS of an Acer Aspire M3800 sets it anyway. Without
setting the bit, coreboot fails to resume from S3. Oscilloscope
measurements have shown that setting the bit increases the delay between
3VSBSW# being set and PWROK2 being set from around 1 us to 140 ms. The
actual use of PWROK2 on the board design is unclear - the only
destination it seems to reach is a pin header near the SuperIO marked as
"GPIO1".

6b5bc77c9b treewide: Remove "this file is part of" lines
Stefan thinks they don't add value.

Command used:

The exceptions are for:
 - crossgcc (patch file)
 - gcov (imported from gcc)
 - elf.h (imported from GNU's libc)
 - nvramtool (more complicated header)

a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

85836c2215 superio: Use 'pnp_devfn_t' over 'device_t' in romstage component
The romstage component of Super I/O support is in fact written around
passing a lower and upper half packed integer. We currently have two
typedef's for this, 'device_t' and 'pnp_devfn_t'. We wish to make use of
'pnp_devfn_t' over 'device_t' as 'device_t' changes it's typedef in the
ramstage context and so is really a conflicting definition. This helps
solve problems down the road to having the 'real' 'device_t' definition
usable in romstage later.

This follows on from the rational given in:
c2956e7 device/pci_early.c: Mixes up variants of a typedefs to 'u32'
