[ Upstream commit 8d9981efbcab066d17af4d3c85c169200f6f78df ]

Order, ids and size  between the table of regmap clocks and the onecell
data table could be different.

Set regmap pointer in all the regmap clocks before starting the
registration using the onecell data, to make sure we don't
get into an incoherent situation.
