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 --- Changes since v4: - Lower the DDR frequency in DCD so that memtester can pass
