Both vdda-1p2-supply and vdda-0p9-supply regulators are controlled
by dp combo phy. Therefore remove them from dp controller.

NOTE: this is somewhat related to Kuogee's series [1] but it's OK to
take even though his series hasn't landed. On trogdor we always keep
these regulators in HPM mode so we're not truly dependent on the
addition of regulator_set_load in the DP PHY.

Subject should have 'dts', not 'dta'.
