sunxi: defconfig: drop redundant definitions

When some configuration symbols were converted from header files to
Kconfig, their values were placed into *every* defconfig file.
Since we now have sensible per-SoC defaults defined in Kconfig, those
values are now redundant, and can just be removed.
This affects CONFIG_SPL_STACK, CONFIG_SYS_PBSIZE, CONFIG_SPL_MAX_SIZE,
and CONFIG_SYS_BOOTM_LEN.
