ARM: socfpga: fix data and tag latency values for pl310 cache controller
The values for the data and tag latency settings on the PL310 caches
controller is an (n-1). For example, the "arm,tag-latency" is specified
as <1 1 1>, so the values that should be written to register should be
0x000. And for the "arm,data-latency" specified as <2 1 1>, the register
value should be 0x010.
