The driver currently hardcodes the device name and the full-scale ADC
codes used to derive the IIO scale attributes. In preparation for
supporting additional parts of the ADE9000 family, move these
part-specific values into a new struct ade9000_chip_info and retrieve it
via spi_get_device_match_data() at probe time.
The channel table and its size are also referenced through the chip_info
so that parts with a different channel layout can be added without
touching the probe path.
No functional change intended for the ADE9000.

The ADE9078 is a polyphase energy metering device from the same family as
the ADE9000. It is register-compatible with the ADE9000 but does not
provide the on-chip dip/swell detection and is limited to a 10 MHz SPI
clock.
Add the new compatible along with a conditional constraint lowering the
maximum spi-max-frequency for the ADE9078.

The ADE9078 is a polyphase energy metering device that is register
compatible with the ADE9000. The main differences relevant to the driver
are the absence of the on-chip dip/swell detection and slightly different
full-scale ADC codes.
Add a dedicated channel table that omits the swell/dip voltage events and
a matching chip_info describing the ADE9078 full-scale codes. The RMS
voltage channel macro is split into a shared base and two variants so the
event-less table can reuse the common definition.
