cpu/allwinner/a10: Fix I2c speed calculation

Looking at the A10 datasheet, N should go in bits 2:0, but
was being cleared by shifting it left by three bits, then
anding it with 7.

Fixes coverity warning:
CID 1241888 (#1 of 1): Wrong operator used (CONSTANT_EXPRESSION_RESULT)
operator_confusion: (n << 3) & (7U /* 7 << 0 */) is always 0 regardless
of the values of its operands. This occurs as the bitwise second operand
of '|'.
