sunxi: Kconfig-ify CONFIG_AXP152_POWER and _AXP209_POWER

Kconfig-ify CONFIG_AXP152_POWER and _AXP209_POWER settings, removing
them from CONFIG_SYS_EXTRA_OPTIONS.

Note that sun5i boards can have either an AXP209 or an AXP152 pmic, the
Kconfig default is AXP209, boards with an AXP152 must explicitly select
this. Likewise boards without a pmic must explicitly select SUNXI_NO_PMIC
in their defconfig.
