feat(ldo): add config to let hardware control the ldo output

Browse Source 
If LDO1 is used by spi flash, then we recommend to give the ownership to
the hardware. Software just read the parameters from the efuse and set
to PMU.

The LDO channel 1 can be used to power the SPI Flash chip,
because the channel 1 is enabled by default after power on reset.
If your SPI flash chip is not powered by ESP internal LDO, you can disable this option.
Then you will free up one LDO channel for other general purpose.

The internal LDO regulator can be used to power the SPI Flash specific power domain.
This option is to select which LDO channel to connect to that domain.
Please set this option correctly according to your schematic.
Set to -1 if the Flash is using any external power supply.
