e78d140b11 mediatek/mt8183: postpone dcxo low power mode setting
Consider the association between modem[1] and DCXO, this patch is a fix for
eb5e47d("mediatek/mt8183: update dcxo output buffer setting") [2]
We should not disable XO_CEL and block the bblpm request when modem is still ON.
For power-saving, we still could disable unused XO_CEL and
mask request to disable unused power mode when modem is no longer be used.

eb5e47dd94 mediatek/mt8183: update dcxo output buffer setting
DCXO consists of core that generates clock and output buffers that
provide clock to other peripheral components.
This patch mainly eliminates the extra power consumption of output buffers.
We only enable the buffer for SOC and disable unused buffers for power-saving.
Also disable useless buffer power mode to guarantee the lowest power state.

fcfa35670a mediatek/mt8183: Enable RTC eosc calibration feature to save power
When system shuts down, RTC enable eosc calibration feature to save
power. Then coreboot RTC driver needs to call rtc_enable_dcxo function
at every boot to switch RTC clock source to dcxo.

b197808852 mediatek/mt8183: Fix RTC initialization flow
1. Fix RTC lpd settings. Rewrite powerkeys after lpd init
   to enable low power detect function.
2. Rearrange RTC initialization flow.
3. Add return status for rtc_init.
4. Add log if calling pwrap_write or pwrap_read fail.
5. Increase timeout time to resolve unexpected timeout.
