arm: imx: Enable always-on regulators using board specific workaround on DHCOM SoM

U-Boot is currently unable to automatically enable regulators which
contain DT property regulator-always-on or regulator-boot-on. There
is an ongoing work to add this functionality to regulator core code,
but until the proper solution lands, add this awful workaround code
to force these regulators on. This is specifically needed to assure
the VIO regulator used to supply ethernet magnetics is enabled.
