Able to build the RSB with CONFIG_SUNXI_RSB and CONFIG_MFD_AXP20X_RSB
and when I replace the above regulator with axp308 dcdc1 for mmc the
SD card is not detecting and the same issue with pine64 as well.

For MFD devices, you need not only the MFD driver, but also drivers for
MFD cells.

For AXP803 currently PEK and regulator cells are supported. The PEK
driver is CONFIG_INPUT_AXP20X_PEK and the regulator driver is
CONFIG_REGULATOR_AXP20X.

I think you missed the CONFIG_REGULATOR_AXP20X driver.
