There are a bunch of other nodes that neeed bootph-pre-ram -> lets first
ensure all the nodes needed for u-boot is present (esm is still in
discussion) then add bootph-pre-ram and related ones in a follow on series.

sure, let's get esm and i2c (pmic one) get concluded,

after that will revisit this.
