The Zii Ultra design, also known as RDU3, is the i.MX8M based successor
to the the i.MX6 based RDU2. This adds the basic board support for all
components which are supported by the upstream kernel at this time.

The board comes in 2 different versions, called RMB3 and Zest, which
are derived from the same design, but have different layouts and a
few small differences in the populated components.

According to the datasheet both industrial and consumer variants support
at least 1.3GHz CPU frequency at 1.0V. Only the OPP at 1.5GHz is
unavailable on some SKUs and thus need further fuse reading support.

According to NXP's FAE feedback and a comment in ATF firmware, PCIE1
and PCIE2 power domains can't really be used independently. Due to
shared reset line both power domains have to be turned on at the same
time. Account for that quirk by combining PCIE power domains into a
single 'pgc_pcie' power domain.
