Iván Briano 867e61cbf3 drivers gpio: Fix disabling of interrupts for QMSI shims
When a GPIO pin is configured, the shim driver will first read the
current values in the controller registers to keep the other pins from
changing their configuration. After that it sets the bits for the
corresponding pin accordingly.

When the flag to enable interrupts is passed to the function, the
corresponding bits are all set properly, but no changes are made if
interrupts are not requested. This makes it impossible to disable
interrupts for a given pin once they've been enabled.

Fix it by always resetting the interrupt enabled bit when they have not
been requested. Other values can be left untouched as they won't have
any effect.

Juan Solano ee623d21de drivers: Remove unnecessary CONFIG_SYS_POWER_DEEP_SLEEP
This commit removes unnecessary CONFIG_SYS_POWER_DEEP_SLEEP protection
in shim drivers as QMSI 1.4 has introduced empty context save/restore
functions that can be called in Quark D2000, therefore keeping common
code at the shim driver level for Quark SE and D2000.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag

deprecated.

New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL

Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug

up, but actually ran afterwards.

- build for x86 needs to define QM_LAKEMONT, as QM_SENSOR was for ARC.

Andre Guedes 3172fca3a0 drivers: qmsi: Fix gpio, i2c and wdt for D2000
This patch fixes the gpio, i2c and watchdog shim drivers so they set the
CLK_PERIPH_CLK bit during driver initialization. Differently from Quark
SE, the peripheral clock gate bit (CLK_PERIPH_CLK) is not enabled by
default in Quark D2000. We have to explicitly set this bit in order to
properly initialize the device.

This issue has been masked so far because the CLK_PERIPH_CLK bit is set
when UART NS16550 driver is enabled. The UART NS16550 driver is enabled
by default for Quark D2000 so gpio, i2c and watchdog sample apps were
working just fine. But if we disable the NS16550 driver, these samples
applications stop working.

The remaining shim drivers already set the CLK_PERIPH_CLK bit during
initialization so there is no need to fix them.

Jesus Sanchez-Palencia 6504b7e72a gpio: Add QMSI-based implementation
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.
