In the initial version of the I2C shim driver, the i2c clock gate was
enabled within i2c_qmsi_configure(). After some review rounds we decided
to move it to i2c_qmsi_init() but missed to remove the clk_periph_disable
call within i2c_qmsi_configure(). So this patch removes it.

CC2520 drivers as a singleton:
Current driver can only handle a single instance. This is due to the
gpio callback which cannot provide the concerned device (not the gpio
device, the cc2520 one). Setting a singleton instance for now, as the
network stack cannot handle more net devices anyway. This will be fixed
in the future.
In the mean time: improving a bit the usage of spi and gpio by accessing
the cc2520 instance directly.
Also: simplifying SPI usage, useless internal locking removed, better
debugging routines, better busy wait macro and use Zephyr's BIT() macro
instead of internal one.

Reading: As when setting up the transfer, Rx has to adapt to current
left Tx lenght.
Writing: If nothing will be transmitted anymore, downsizing the level to
0. This fixes a hanging issue while making the controller being busy for
nothing. Another hack found to fix the same issue was to test the SR
Busy flag bit in the ISR handler. As the threshold level makes more
sense, kepping this one.

Introduce the GPIO QMSI-based implementation. This is basically a
shim layer that implement's Zephyr's GPIO APIs on top of QMSI drivers.
This is an alternative driver that conflicts with the previous
GPIO_DW implementation. In order to enable it you must set:
- CONFIG_GPIO=n
- CONFIG_GPIO_QMSI=y
- CONFIG_GPIO_0=y
- CONFIG_QMSI_DRIVERS=y
- CONFIG_QMSI_INTALL_PATH="PATH_TO_QMSI"
Note that this driver currently only supports one controller instance,
GPIO_0. It is implemented this way due to a limitation from the current
version of QMSI. QMSI versions later than 1.0 doesn't have this
limitation.
Missing:
- support multiple controller instances (gpio_0, gpio_1, etc);
- enable level triggered interrupts in sync with system clock,
through setting INT_CLOCK_SYNC properly.

This commit changes the behavior of the driver when it reports
buffer results back through the callback.
Originally, the driver reported a callback after each sequence
table round signaled by an interrupt. If in repetitive mode,
each reported result was put in the next buffer element,
which was considered circular, and reported back with callback.
Now the behavior changes. If in repetitive mode, each sequence table
round reported by an interruption puts the data in next element of
the reception buffer. The callback reports back once the buffer is
fulled and stops the sampling process.
