In order to restore i2c context after entering
SYS_PM_DEEP_SLEEP, suspend and resume functions
are called.
The following parameters are restored:
- All registers for the I2C device.
- I2C clocks.
I2C depends on the DMA which is enabled separately.
The suspend/resume functionality is implemented in
the QMSI shim layer as a fast and temporary solution,
it will be removed and migrated to QMSI later.

Fix a compilation warning. Compilation of the i2c driver
requires QMSI dma object file. As a solution, the current
code has "selects DMA_QMSI" in i2c Kconfig. This results
in a compilation warning since "select DMA" is also
required. Adding "select DMA" and "select DMA_QMSI"
together in i2c Kconfig can solve the compilation issue.
But, this will cause the dma driver be unnecessarily
enabled. So, the solution is to fix the issue in the QMSI
part instead of in the shim driver.

Update the QMSI drop we maintain in Zephyr and
keep the modification to qm_soc_regs.h introduced on commit
6b88a6b945 "ext qmsi: Add USB base and interrupt defines" since
that patch hasn't made into the QMSI 1.1-Beta release in time.
Also, fix the build where needed:
- add hard dependency from qm_i2c to qm_dma
- fix spi_qmsi_ss.c due to new parameter naming
- fix adc_qmsi.c and adc_qmsi_ss.c due to a new parameter

This patch extends the i2c shim driver so it supports the 'default
configuration' infrastructure which enables the user to specify a
default configuration for the I2C device. The default configuration
is set during driver initialization.
This patch also changes Quark SE and D2000 Kconfig.defconfig files so
the i2c default configuration is set to '0x12' which means standard
bus speed, 7-bit addressing and master mode. This is the same value
used when DW driver is selected, by the way.

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.
