Samsung Manta: improve battery support, add sensors, fix WiFi and RTC

This MR proposes the changes described below.

Improve battery support:

• DT support for DS2482/DS2484 I2C<->W1 bridge
• Add support for DS2484 sleep GPIO
• improvement to the smb347-charger, as per discussion in postmarketOS/pmaports#2534 (moved) (cc @rumpel)

Add support for sensors:

• BMP182 (pressure)
• BH1750 (light)
• MPU6050 (IMU)
• AK8963 (magnetometer) -> Looking for a way to check the orientation matrix on this one

Fix WiFi:

• WiFi was slow and caused many messages in dmesg, due to the bus being configured at too high of a speed. The original value was the one from the downstream kernel, but digging a bit revealed that several users experienced WiFi slowdowns on Nexus10 stock.

Fix RTC:

• S3C RTC seems to be broken on this device. Proposal to not enable it so that userspace automatically use the working MAX77686 RTC.
• See postmarketOS/pmaports!4783 (comment 1762878848) (cc @knuxify, @jenneron).

Misc:

• updated defconfig
• fix display on some devices (and dmesg complains about it on most, maybe all). See postmarketOS/pmaports#2615.
• 7461591a could be merged with f2a4eaff, since it is just that CLKS_NR was moved from bindings to clock drivers in 835dc5ac.
