LCD4 needs a slightly different GPIO configuration than the
original LWMON5 variant. GPIO49 needs to be configured to a
default output value of 0 (permanent voltage supply).

Additionally lcd4 also needs to enable the LSB transmitter.

For most boards which define CONFIG_SPL_PAD_TO,
it is defined in config header files.
Currently, there exists only one exception, cam_enc_4xx board.

This patch moves CONFIG_SPL_PAD_TO definition
from board/ait/cam_enc_4xx/config.mk
to include/configs/cam_enc_4xx.h.

With this modification, we can delete a glue code
in the top level config.mk:

ifneq ($(CONFIG_SPL_PAD_TO),)
CPPFLAGS += -DCONFIG_SPL_PAD_TO=$(CONFIG_SPL_PAD_TO)
endif

libata already has similar functions as implemented in the ahci code.
Refactor the code to use the libata variants and remove the dependency on
ata.h. Convert some defines to use the version from libata.h. Also, remove
some unnecessary memset's of bss data.

This is a step toward hopefully merging ahci.c and dw_ahsata.c which are
essentially the same driver.
