ee41561d9c ARM: dts: stm32: keep uart nodes behavior on stm32mp157a-stinger96
DMA configuration is added to uart nodes in stm32mp15x device tree.
Delete uart4 DMA property in stm32mp157a-stinger96 board device tree to
keep console in irq mode, as DMA support for console has been removed
from the driver by commit e359b4411c ("serial: stm32: fix threaded
interrupt handling").
Delete also usart2 and uart7 DMA property to keep current behavior.

4bf4abe190 ARM: dts: stm32: fix stpmic node for stm32mp1 boards
On some STM32 MP15 boards, stpmic node is not correct which generates
warnings running "make dtbs_check W=1" command. Issues are:

-"regulator-active-discharge" is not a boolean but an uint32.
-"regulator-over-current-protection" is not a valid entry for vref_ddr.
-LDO4 has a fixed voltage (3v3) so min/max entries are not allowed.

c96f8d3ca7 ARM: dts: stm32: remove usbphyc ports vdda1v1 & vdda1v8 on stm32mp15 boards
vdda1v1 and vdda1v8 supplies are required by USB PLL, not by the PHYs.
Remove them from usbphyc child phy nodes now that they are managed in
usbphyc parent node at SoC level.
