Enable cache operations before starting a DMA operation if the CPU has a
cache. All the support was already in place, it just needs to be
enabled.
With the previous commits, it allows the I2S tests to pass on a SAM E70
Xplained board with the CPU cache enabled.

This effectively reverts part of earlier 49bb163756 which moved
interrupt acknowledgement until after return from the user callback.
This was done confusing the flow of this driver with how some other
drivers do it, where pending interrupt status is checked by
uart_irq_rx_ready()/uart_irq_tx_ready(), which should be called by
the callback. But the uart_cmsdk_apb driver actually uses different
hardware register in these functions. And acking IRQs after user
callback can lead to race condition and losing an IRQ, and the
simple fix in this case is just move acknowledgement to where it
was before.

Nordic USB driver shim uses nrfx_usbd driver from nrfx package.
The driver was protected by a semaphore during every transfer
to prevent access from multiple threads at the same time.
This leads to the problem when a class schedules transfer on one
endpoint before host asks for the data (to be sent later) - driver
is locked and other endpoints (including control EP) are blocked.
Currently, only driver calls are wrapped with semaphore without
waiting for the transfer to complete, allowing scheduling transfers
on different endpoints. This is allowed bu nrfx_usbd, however
shim prevents user from scheduling multiple transfers on one
EP (required by nrfx_usbd).

Modem driver for WNCM14A2A was erroneously leaving the
selection of UART_INTERRUPT_DRIVEN up to CONSOLE_HANDLER.
Now, with the move to the new SHELL backend, this is no
longer happening.
Let's select it from the modem driver, instead of depending
on it.
Let's also add a dependency on SERIAL_SUPPORT_INTERRUPT
which the serial drivers enable to let us know
UART_INTERRUPT_DRIVEN is available.

When users are configuring applications they are given the option
to enable the DesignWare SPI driver. But they should not be given this
option on SoCs that don't have the DesignWare SPI HW.
This commit hides the driver by default by introducing the config
option HAS_SPI_DW.

This patch adds a flash driver for the Atmel SAM E70 SoC. The driver has
been kept simple by considering that the flash is only composed of 8-KiB
blocks. Indeed an area at the beginning of the flash might be erased
with a smaller granularity, and the other blocks can also be erased with
a higher granularity. It also only handles the global read/write
protection, not the 128-KiB lock regions. A write error is returned if
a region is locked.

The Zephyr console and shell interrupt processing assumes
a TX interrupt is evoked upon first enabling the TX
interrupt via uart_irq_tx_enable.
This was not the case with the cc32xx uart, coming out of
reset, with FIFO's disabled.
The only way found to achieve this behavior is to fill
the fifo with a non-printable character on initialization.
Also, the uart driver was explicitly clearing TX/RX interrupts in
its isr, which was unnecessary, as the act of reading/writing
did that implicitly.
These fixes allow the cc32xx uart to work with the
current Zephyr console/shell design.

1. There's an expectations that TX ready (i.e. TX buffer space
available) interrupt is a level interrupt, i.e. always active
while there's TX buffer space available. In particular, there's
an expectation that after uart_irq_tx_enable(), the TX interrupt
will immediately fire (assuming free TX buffer space is available).
But CMSDK UART interrupt appears to be edge interrupt, firing only
on buffer state change. So, after irq_tx_enable(), we need to
"bootstrap" interrupt processing by calling user-defined ISR
manually (the ISR will see that TX ready to accept a new char,
will write it there, then we'll get interrupt once TX buffer is
ready again).
2. Interrupts should be acknowledges only after user ISR is called,
because the ISR will check the status of interrupts.
3. Update stale comments.
