System ACE compact flash controller supports either 8-bit (default) or
16-bit data transfers. And in corresponding driver we need to implement
read/write of 16-bit data words properly for both modes of operation.
In existing code if width==8 both branches get executed which may cause
unexpected behavior of SystemAce controller.
Addition of "else" fixes described issue and execution is done as
expected for both (8-bit and 16-bit) data bus widths.

prototype in "block_dev_desc_t"
Currently we have "unsigned long blkcnt" which is fine with
CONFIG_SYS_64BIT_LBA undefined because "lbaint_t" is basically the same
"unsigned long".
If CONFIG_SYS_64BIT_LBA gets defined "lbaint_t" is defined as "unsigned
long long".
Even though not many embedded systems have CONFIG_SYS_64BIT_LBA defined
it's good to have types in function implementation that match exactly
with prototypes.

Use CONFIG parameters only at one location to simplify
the code. Also create ace_readw/writew functions.

If we don't want to build support for any partition types we can now
add #undef CONFIG_PARTITIONS in a board config file to keep this from
being compiled in. Otherwise boards assume this is compiled in by
default
