dt-bindings: mfd: mediatek: mt6397: describe the RTC's nvmem layout
Four of the MT6397 RTC's alarm registers use only their low bits; the
high byte of each is storage the clock and the alarm don't touch.
MediaTek's documentation names them RTC_NEW_SPARE0 to RTC_NEW_SPARE3 and
assigns the first to a fuel gauge, which is what a battery driver reads
at boot so that the reported capacity does not jump across a reboot.
They sit in the RTC's always-on domain, so the driver can offer them as
a battery-backed nvmem provider. Allow a board to lay cells out over
them.
