[U-Boot] [PATCH] i2c:mxc fix array size of i2c_data

We should not hardcode array size of i2c_data to 3. To CONFIG_FSL_LSCH3,
there are 4 i2c interface, but not 3. So the size of i2c_data array should
be calculated using "ARRAY_SIZE(i2c_bases)".

To avoid compile error, move i2c_bases before sram_data structure which
contains i2c_data array.
