As both MMC and GPIO driver now supports OF_PLATDATA, enable it in
defconfig in order to reduce the SPL footprint. After applying this
setting the SPL reduction is 5 KB, which partially compensates the
increment due to DM.

This introduces support for EEPROM as a storage for the main Toradex
config block and additional config blocks on extra EEPROM chips (on
carrier board or video adapters).

To enable EEPROM as a storage for the main config block:
TDX_HAVE_EEPROM=y.

For additional EEPROMs please enable this Kconfig symbol:
TDX_CFG_BLOCK_EXTRA=y.

Information about existing EEPROM chips is provided via Device Tree
using aliases.

You can also write configuration for the carrier board using
create_carrier subcommand for cfgblock. Example:

Verdin iMX8MM # cfgblock create_carrier
Supported carrier boards:
UNKNOWN CARRIER                     = [0]
Verdin Carrier Board                = [1]
Choose your carrier board (provide ID): 1
Enter carrier board version (e.g. V1.1B): V1.0A
Enter carrier board serial number: 10622780

Per the DT binding, <mask> and <value> property can have either one

This adds support to the <value> property to the driver, and <mask>
semantics is updated to really be a mask to the value if both exist.
