The "write protect" GPIO's cached value is never actually
read after entering depthcharge. Ensure the value from
get_write_protect_state() is being transferred accurately,
so that we may read this GPIO value in depthcharge without
resampling.
The cached value of the "recovery" GPIO is read only on certain
boards which have a physical recovery switch. Correct some of
the values sent to boards which presumably never read the
previously incorrect value. Most of these inaccuracies are from
non-inverted values on ACTIVE_LOW GPIOs.

This check had very few false positives which were all easily resolved,
and it's unlikely that further false positives will become problematic
in the future. On the other hand, it does detect a very severe bug (when
you think you're using a Kconfig but you aren't due to a typo), so since
warnings are currently not very visible, let's turn this into an error
because the pros clearly outweigh the cons for that.

Our strtol() and strtoull() function contain almost exactly the same
code. This is a) bad in general and b) may cause the code to get out of
sync, such as it recently happened with CB:32029.
This patch changes strtol() to be based on strtoull() so that the main
parsing code exists only once, and also adds a strtoll() to round off
the library. Also fix the bounds imposed by strtoul() to be based on the
actual length of a 'long', not hardcoded to 32-bits (which is not
equivalent on all architectures).

Our current limits.h only provides (U)INT_MAX constants. This patch adds
most others expected by POSIX. Since some of these may be different
depending on architecture (e.g. 'long' is 32-bit on x86 and 64-bit on
arm64), provide a definition that will automatically figure out the
right value for the data model the compiler is using (as long as it's
using two's complement for signed integers, which I think we can assume
these days).

New compilers are a little more stringent about defining the same
prototype more than once, so some of our CONFIG_LP_DEBUG_MALLOC wrappers
don't quite work the way they are written anymore. Also, several of the
printf()s weren't written 64-bit safe. And let's add some
double-evaluation safety while I'm here anyway... and I have no idea why
this ever depended on CONFIG_LP_USB, that just seems like a typo.

lsbpos and msbpos have incorrect behaviour when given 0.
lsbpos(0) returns 8, and msbpos(0) hangs. The latter is
because the check i >= 0 is always true for an unsigned
integer, causing it to loop indefinitely (this was flagged
by Coverity).
0 doesn't have a lsb or msb position, so we change both
functions to return -1 in this case to indicate an error.
The code already guards against calling these functions
with 0, but we make this more explicit to prevent errors
in the future.

The effect of pointer aliasing on writes is that any data on CPU
registers that has been resolved from (non-const and non-volatile)
memory objects has to be discarded and resolved. In other words, the
compiler assumes that a pointer that does not have an absolute value
at build-time, and is of type 'void *' or 'char *', may write over
any memory object.
Using a unique datatype for MMIO writes makes the pointer to _not_
qualify for pointer aliasing with any other objects in memory. This
avoid constantly resolving the PCI MMCONF address, which is a derived
value from a 'struct device *'.

FSP options list (for each PEG port):
- PegXEnable,
- PegXMaxLinkWidth,
- PegXMaxLinkSpeed,
- PegXPowerDownUnusedLanes,
- PegXGen3EqPh2Enable,
- PegXGen3EqPh3Method.
Add PegMaxLinkWidth to chip.h. This option overrides the number of
active lines from the devicetree.cb for each enabled PEG port (for
example for boards that use x4 instead of x16 lines in PEG0). If the
PegMaxLinkWidth is not defined, the port uses the maximum possible
number of lines.
To enable or disable the corresponding PEG root port you need to add
to the devicetree.cb:
device pci 01.0 on end # enable PEG0 root port
device pci 01.1 off end # do not configure PEG1
If PEG port is not defined in the devicetree, it will be disabled in
FSP.
It has been tested on ASRock H110M-DVS motherboard (Skylake i5-6600
CPU).
