imx: i2c: Zap unnecessary malloc() calls

The malloc() calls are unnecessary, just allocate the stuff on stack.
While at it, reorder the code a little, so that only one variable is
used for the text, use snprintf() instead of sprintf() and use %01d
as a formatting string to avoid any possible overflows.
