After powering-on the sensor, and before every measurement, it loads
the NMV. We must wait until this process is completed otherwise
we will read weird values.
Since it was observed that the time may be a bit long after a cold
start, it is more convinient to just wait until the sensor iready,
without a timout.

To ensure that we have the same behaviour with a power cycle
and by pressing the reset button, we can perform soft reset
in `bme280_chip_init()`.

Move the SPI and I2C bus I/O bits into their own files. This makes
this driver more similar to other sensor drivers.

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Move logging out of misc/ to its own subsystem. Anything related to
logging and any new logging features or backends could be added here
instead of the generic location in misc/ which is overcrowded with
options that are not related to eachother.
