Rpi5 RTC documentation is outdated #4205
Description
In the docs at https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#real-time-clock-rtc , it gives sysfs examples
such as "/sys/devices/platform/soc/soc:rpi_rtc/rtc/rtc0/charging_voltage" but this sysfs path seemingly changed mid-stream for
Bookworm (which is aggravating). Anyway, now it seems to be "/sys/devices/platform/soc@107c000000/soc@107c000000:rpi_rtc/rtc/rtc0/charging_voltage".
It also might be good to add how to identify the official Raspberry Pi rechargable RTC battery. Some are in a yellow colored heat shrink cover, others might be in a white colored one.
