Bananapi R4 Board contains a MT6682A pmic which is compatible to rt5190a.
Add its node to the i2 controller.
The BananaPi R4 board has a MediaTek MT6682A PMIC, a rebrand of the
Richtek RT5190A chip, connected to the I2C0 bus.
Add the relevant node and, while at it, also configure the regulators
from this PMIC that are used on this board.
Only Buck2/Buck3 voltage can be controlled by software.
BUCK4 input is 5V from BUCK1 output, and the resistor (mapped to RP30/RP31
on BPI-R4) configures BUCK4 output to 1.8V.
LDO input is 3.3V from 3.3VD, and the resistor (mapped to RP38/RP40 on
BPI-R4) configures LDO output to 1.8V.

The MAC reset for PCIe port 1 on MT8195 when asserted during suspend
causes the system to hang during resume with the following error (with
no_console_suspend enabled):
mtk-pcie-gen3 112f8000.pcie: PCIe link down, current LTSSM state: detect.quiet (0x0)
mtk-pcie-gen3 112f8000.pcie: PM: dpm_run_callback(): genpd_resume_noirq+0x0/0x24 returns -110
mtk-pcie-gen3 112f8000.pcie: PM: failed to resume noirq: error -110
This issue is specific to MT8195. On MT8192 with the PCIe reset,
MT8192_INFRA_RST4_PCIE_TOP_SWRST, added to the DT node, the issue is not
observed.
Since without the reset, the PCIe controller and WiFi card connected to
it, work just as well, remove the reset to allow the system to suspend
and resume properly.

The MT6397 PMIC bindings specify exact names for its sub-nodes. The
names used in the current dts don't match, causing a validation error.
Fix up the names. Also drop the label for the regulators node, since
any reference should be against the individual regulator sub-nodes.

The "regulator-compatible" property has been deprecated since 2012 in
commit 13511def87 ("regulator: deprecate regulator-compatible DT
property"), which is so old it's not even mentioned in the converted
regulator bindings YAML file. It should not have been used for new
submissions such as the MT6315.
Drop the "regulator-compatible" property from the board dts. The
property values are the same as the node name, so everything should
continue to work.

Most SoC dtsi files have the display output interfaces disabled by
default, and only enabled on boards that utilize them. The MT8183
has it backwards: the display outputs are left enabled by default,
and only disabled at the board level.
Reverse the situation for the DSI output so that it follows the
normal scheme. For ease of backporting the DPI output is handled
in a separate patch.
