The code was so far requesting 5 ms refresh timer, however with a
default TICKS_PER_SECOND=100 this was always rounded up to 10 ms,
causing some flickering. The closest TICKS_PER_SECOND that will give
flicker-less display but also give optimal ms-to-ticks calculations is
250, so change the timer to match that. After this change any code
using the display is recommended to set 250 as ticks per second.

If CS is controlled over GPIO, it will be possible to keep the slave up
and running (though no transaction will be going on) using this
configuration bit.
Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>
SPI_HOLD_ON_CS can be used to ask the SPI device to keep CS on, after
the transaction. And this undefinitely, until another config is used.
This will inhibate the gpio cs delay, if any. This might be useful when
doing consecutive calls on one slave without releasing the CS.
SPI_LOCK_ON is to be used with caution as it will keep the SPI device
locked for the current config being used after each transaction. This
can be necessary if one needs to do consecutive calls on a slave without
any olher caller to interfere.

Adding a struct k_poll_signal parameter to driver's API unique
exposed function.
If not NULL, the call will be handled as asynchronous and will
return right after the transaction has started, on the contrary
of current logic where is waits for the transaction to finish
(= synchronous).
In order to save stack, let's move the device pointer to struct
spi_config. So the call is still at a maximum of 4 parameters.
Adapting spi_dw.c and spi driver sample to the change so it still
builts.

All SPI drivers have this same way to handle synchronous call, thus
let's generalize it in struct spi_context, with a relevant API and apply
the change into SPI DW driver.
spi_context API will prove to be useful once asynchronous call will be
handled as well, through the same completion functions used now only for
synchronous call. It will be transparent for the driver.

Such API improves many aspects of the former API by reducing the number
of function, allowing more buffer flexibility etc... This leads in
better memory usag and performance as well.
However, as this will take sometime to get into use, the former API is
still present and is the one enabled by default.

The STM32L4x SoCs embeds a slightly different embedded flash controller
from the STM32F4x SoCs.
This particular controller has the following properties :
- Up to 2 512KiB banks divided in 2KiB pages
- Flash can be accessed in any sizes
- Flash must be written in 64bit aligned 64bit double-words
The drivers/flash/flash_stm32f4x.c is refactored into a new common
drivers/flash/flash_stm32.c and drivers/flash/flash_stm32l4x.c is
created with the STM32L4x specific functions.
To ease the refactoring and keep common functions, the STM32L4x flash
headers are slightly modified to match the hardware reference naming
and solve compilation issues.

uart_irq_tx_empty() function proved to be problematic: its semantics
was not documented properly, and many hardware uses terminology like
"TX register empty" to signify condition of TX register being ready
to accept another character (what in Zephyr is tested with
uart_irq_tx_ready()). To avoid confusion, uart_irq_tx_empty() was
renamed to uart_irq_tx_complete(), propagating to drivers/serial
device methods.
The semantics and usage model of all of uart_irq_rx_ready(),
uart_irq_tx_ready(), uart_irq_tx_complete() is now described in
