This patch adds the resources and DMI ID's for the MEN SC31,
which uses a different address region to map the LPC bus than
the one used for the existing SC24.

NVMEM has been in kernel since v4.2 but the ABI document was missing
since then. userspace interface did not change since then and seems
stable, so this patch documents the nvmem ABI.

The value passed into the perf.data file for the CONFIGR register in ETMv4
was incorrectly being set to the command line options/ETMv3 value.
Adds bit definitions and function to remap this value to the correct ETMv4
CONFIGR bit values for all selected options.

missing err.h header file can cause simillar errors like below
in some configurations.
"error: implicit declaration of function 'ERR_PTR'
[-Werror=implicit-function-declaration]"
This adds the missing include to ensure we can always include

"p" is the list iterator so it can't be NULL. Static checkers complain
about this unnecessary check because we dereference the list iterator to
get the next item in the list so we'd be in trouble if it really was
NULL. I have removed the check.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.
No functional changes.

The functions w1_ds2438_get_page, w1_ds2438_get_temperature,
w1_ds2438_change_config_bit and w1_ds2438_get_voltage are local to
the source and do not need to be in global scope, so make it static.
Cleans up sparse warnings:
symbol 'w1_ds2438_get_page' was not declared. Should it be static?
symbol 'w1_ds2438_get_temperature' was not declared. Should it be static?

o Make endian clean, make HW-endianness configurable.
o Use ioread*, iowrite* instead of __raw_readb,__raw_writeb
to also use memory-barriers when accessing HW-registers.
We do not want reordering to happen here.
