Add an "iommus" property to the IPA node in "sdm845.dtsi". It is
required because there are two regions of memory the IPA accesses
through an SMMU. The next few patches define and map those regions.

Enable CPU and GPU opp tables for Pine H64.
This needs to change the CPU regulator max voltage to fit
the OPP table.
Also add the ramp-delay information to avoid any out of spec
running as the regulator is slower at reaching the voltage
requested compare to the PLL reaching the frequency.
There is no such information for AXP805 but similar PMIC (AXP813)
has a DVM (Dynamic Voltage scaling Management) ramp rate equal
to 2500uV/us.

The extended mainscaler is only available on FIMC1 and there

Additionally, the cam-if interface is available on all three

The node name was gpgi, but the pinctrl driver was registering the pins
as just gpi and the "samsung,pins" i2s0 pinctrl entries refer to gpi.
The public S5PC110 datasheet also refers to these pins as just gpi,
so let's make sure everything is in sync and rename the node to gpi.
