de4727ba3f sensor: update drivers to not return double values
Update drivers to return INT_PLUS_MICRO values instead of doubles.

This hides the fact that the drivers use floating point operations and
doesn't force the application to use them as well.

c3e08c8fea net: buf: Redesigned pool & buffer allocation API
Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".

This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:

	NET_BUF_POOL_DEFINE(pool_name, ...);

Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.

This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.

a715194d43 random: Rewrite sys_rand32_init() with SYS_INIT()
Use the SYS_INIT() mechanism to invoke the sys_rand32_init() function
in random drivers that require an initializer.  Remove all empty
sys_rand32_init() instances.

The existing explicit sys_rand32_init() function runs immediately after
PRE_KERNEL_2 before stack canaries are initialized.  In order to get
equivalent behaviour with sys_rand32_init() we set SYS_INIT() to
initialize the random drivers at the lowest priority of PRE_KERNEL_2.

a4e823eee0 pinmux: Introduce new ksdk pinmux driver
Kinetis SoCs contain one or more PORT modules to handle pin muxing and
pin configuration. Unlike the existing k64 pinmux driver, this driver
handles each PORT module individually and can be used for other Kinetis
SoCs.

This driver uses KSDK CMSIS register accesses to the PORT module rather
than the KSDK PORT driver (fsl_port.h), because the Zephyr pinmux
interface contains both set() and get() functions to access the pin
configuration. The KSDK PORT driver only contains a set() function
(which is a very thin static inline function to modify the PCR
register), therefore building a shim on top of it would result in a
strange mix of using the KSDK PORT driver for the set() and a direct
CMSIS register access for the get().

212f5f28ed drivers: spi_k64: Fix RX overflow
This patch fixes RX overflow error in the k64 SPI driver.

Jira: ZEP-1351
Jira: ZEP-1352

Several circumstances lead to an RX overflow:

The RFOF_RE (RX fifo overflow) must not be set as default.
The flag is only set when rx_buf is available. Also it must
be checked inside spi_k64_isr whether RFOF_RE has been set or not.

If the rx_buf is not available and the incoming data
should be ignored, then MCR_ROOE need to be set.
Since it is not possible to change the MCR register
during the transfer, RX fifo must be emptied
if rx_buf_len < tx_buf_len.

The driver also uses spi_data.xfer_len now,
the variable was already defined. Now, transfers are also
possible if tx_buf_len < rx_buf_len (e.g. read slave device register).
spi_k64_push_data has been adjusted accordingly.

The patch simplifies the handling of interrupts.
The interrupts are also switched off in the event of an error.

The patch also fixes a few coding style issues.
