of: Fix iteration bug over CPU reg properties
The size of each hwid in a cpu nodes 'reg' property is defined by the
parents #address-cells property in the normal way. The cpu parsing code
has a bug where it will overrun the end of the property if
address-cells is greater than one. This commit fixes the problem by
adjusting the array size by the number of address cells. It also makes
sure address-cells isn't zero for that would cause an infinite loop.
v2: bail if #address-cells is zero instead of forcing to
OF_ROOT_NODE_ADDR_CELLS_DEFAULT. Forcing it will cause the reg
property to be parsed incorrectly.
