[U-Boot] [PATCH] drivers/block/systemace: fixes read/write words for bus width = 8

[Alexey Brodkin]

From: Alexey Brodkin <abrodkin at synopsys.com>

Current implementation works fine for bus width = 16 bits because we
never get into "if" branch.

If one sets width to 8 bits there will be 2 consequent data accesses
(read/write):
1. Correct data access for 8-bit bus
2. Unconditional (and in this case incorrect) data access as if data bus
is 16-bit wide
