DCDC5 is designed to supply VCC-DRAM, which is normally 1.5V for DDR3,
1.35V for DDR3L, and 1.2V for LPDDR3.
Also remove CONFIG_AXP_DCDC5_VOLT from h8_homlet_v2_defconfig.

Set the voltage (mV) to program the axp pmic dcdc5 at, set to 0 to
disable dcdc5.
On A23 / A31 / A33 / A83T boards dcdc5 is VCC-DRAM and should be 1.5V,
