From: Caleb Ethridge <caleb.ethridge@analog.com>

This patch series does some small cleanup of the Kconfig options for the
sc5xx boards. Common code for the SOMCRR carrier boards is now only built
when one of the carrier boards is selected. Previously, it was built
unconditionally which resulted in dead code.

The series also fixes a bug with the sc594 EZLITE where it was being built
with the EZKIT carrier code, resulting in the Ethernet not being set up
properly. As the carrier board Kconfig option was a choice, the select from
the TARGET was being ignored and the fallback was the default EZKIT code.
Carrier board options have been changed from choices to bools so that the
board targets can select the carrier board properly.

Also, removing the explicit carrier board option from the sc598 EZLITE, since
with the change to the bool options for the carrier boards it is no longer
needed.

somcrr_common.c calls adi_somcrr_enable_ethernet() and
adi_somcrr_disable_ethernet(), which are only provided by the
carrier-specific files. It is built unconditionally, so a SOM built
without a carrier board would be left with undefined references.

Add an ADI_CARRIER_SOMCRR_COMMON symbol, selected by each carrier
board option, and only build somcrr_common.o when it is enabled.

From: Caleb Ethridge <caleb.ethridge@analog.com>

The TARGET_SC5xx_SOM_* board options pick their carrier board with
"select ADI_CARRIER_SOMCRR_*", but the carrier options are members of a
choice and Kconfig ignores select on choice values. The carrier always
fell back to the choice default instead, so the sc594-som-ezlite was built
with the EZKIT carrier code.

Turn the carrier options into plain bool symbols so that we can
leverage the existing selects in the board targets.
