Use SYS_NAND_SELF_INIT and only setup the pinmux and clocks when we are
actually using the nand.

In syndrome mode we set the NFC_SEQ bit in the command register, so the
spare-area register is not used. Also the value currently being written is
actual wrong, the ecc sits at "column + CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE"
not just CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE.
So the current code only serves to confuse the user -> remove it.

There is no need to reset the nand chip for every ecc-block read.

nand_spl_load_image() always gets called with either CONFIG_SYS_TEXT_BASE
or spl_image.load_addr as destination, both of which are properly aligened,
and have plenty of space for "overshooting" up to
CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE bytes, as we read in
CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE bytes chunks.
This saves CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE (typically 1k) in
SPL size, which is a lot on the total 24k we have.
Note this changes the dma destination from SRAM to DRAM, so this patch
updates the DDMA_DST_TYPE bits in the dma controller cfg0 reg accordingly.

This driver adds NAND support to SPL.
It was tested on Allwinner A20.

This commit adds support to the sunxi SPL to load u-boot from the internal
NAND. Note this only adds support to access the boot partitions to load
u-boot, full NAND support to load the kernel, etc. from the nand data
partition will come later.
