Move power configuration from the device init function into the
`DISK_IOCTL_CTRL_INIT` and `DISK_IOCTL_CTRL_DEINIT` handlers. If
`pwr-gpios` is defined, this ensures that the card is not powered up
until requested, and enables power down the card when not in use.
This behaviour matches the implementation for `sdhc_spi`.

Add the option to specify an alternate ADC gain value to use if the
initial measurement saturates the range. This enables higher data
resolutions when the values are small compared to the maximum signal
values, while still supporting the maximum.
As a concrete example, measuring charge currents from a small solar
panel (0 - 50mA), while also supporting high USB charge currents
(up to 1A).

According to the LIS2DU12 datasheet (p.30), the device must be
inpower-down mode before executing a software reset.
Entering power-down requires setting the ODR field to 0x000.
This commit adds the missing call to set ODR=0x000 before issuing the
reset. Without this step, the sensor does not recover after a controller
reset and only resumes operation after a full power cycle.

Add a driver for the VIRTIO Ethernet device.
This is a minimal driver which sets a MAC address and transmits packets,
but does not support any extra features like the control channel or
checksum offloading.
Confirmed to work with the networking subsystem samples. For example, the
zperf sample shows a result of 85 Mbps download and 14 Mbps upload.

The UDC stack assumes that 'halt' on control endpoints is automatically
cleared by device drivers and never calls udc_ep_clear_halt() for such
endpoints. In practice, most controllers do perform this automatic clear
in hardware, but this requires special handling in udc_ep_set_halt() for
control endpoints (EP0), as setting the 'halted' bit on such endpoints will
lead to the software getting out-of-sync with the hardware.
Update the UDC skeleton driver to handle this edge case and add a comment
documenting the stack's behavior, along with the hardware behavior expected
by the code added to the skeleton driver for it to be functional.

Explicitly configure retention mode when powering up HPSRAM banks to
ensure consistent behavior across hardware platforms.
After D3 power state transitions, the retention mode configuration can
become undefined due to hardware reset. This causes test failures in NVL
FPGA testing environment where the hardware strictly enforces retention
mode settings.
The fix ensures retention mode is properly set in two locations:
- sys_mm_drv_hpsram_pwr(): Configure retention mode for all bank
power-up operations
- adsp_mm_restore_context(): Explicitly set retention mode during
D3->D0 restore sequence after each bank is powered up
