This commit introduces a new api for the net layer of Dallas
1-wire protocol.
For single drop configurations w1_read_rom, and w1_skip_rom commands are
provided.
For multidrop configurations w1_match_rom, w1_resume_command,
w1_search_rom, and w1_search_alarm routines are provided as well.
Additionally, the reset_select routine, conditionally depending on the
bus configuration, either executes a match_rom, or a skip rom command.
A w1_write_read command simplifies the typical scenario of addressing
a device, writing a few bytes to the device and reading back the answer.
Additionally w1_crc8, and w1_crc16 are added as wrappers around the
zephyr in-tree crc8 and crc16_reflect implementations.
The former may be used to verify the validity of the rom id, while the
latter is used for integrity checking of many eeprom, and authenticator
commands.
The general search command does not support filtering on
the family code.

This commit introduces a new api for the Dallas 1-wire protocol.
The api includes link functions for read and write operations on
bit, byte, and block level, as well as functions to reset and
lock the bus.
The bus configuration is derived from the device tree and can be
queried using w1_slave_count routine.

The EFI console output call return with interrput enabled, it is a
firmware bug. And there was a solution that disabled interrupt it
return right away. But in some case the interrupt could happen
during the efi call context. If an interrupt was handled, a printk
call again will make it re-entried, or a swap might be happens.
This is suggested solution appiled for EFI console output:
1. Skip printk call when it is called in interrupt context.
2. Disable the schedule during the EFI call window.

Due to the limitation of the current x86 EFI cosnole implementation,
we skip hte printk which is called by tracing API:
sys_trace_thread_switched_in_user/out_user.

Add a EFI console logging backend to support logging sub-system.
To fix those testcases have no log output due to no logging backend.

Add a minimal EFI console driver to support printf, this console driver
only supports console output. Otherwise the printf will not work.

The main CMakeLists.txt for hal_atmel adds an include directory
without checking that the module is enabled. This causes ALL Zephyr
builds to have modules/hal/atmel/include in their included
directories. This commit updates west.yml to point to a fix for
this issue.

Since `CONFIG_GETOPT=y` is specified in `prj.conf`,
it does not make sense to filter for `CONFIG_GETOPT`.
Additionally, we should run a permutation explicitly
with newlib, for consistency.

This is all static functions that can maintained outside of the class
and called only in one place, so move this to the testsuite file.
