mx7ulp: Add support for Embedded Artists COM board
The Embedded Artists COM board is based on NXP i.MX7ULP. It has a BD70528 PMIC from Rohm with discrete DCDC powering option and improved current observability (compared to the existing NXP i.MX7ULP EVK). Add the initial support for the board. Signed-off-by: Fabio Estevam <festevam@gmail.com>
