misc: (at24) move header to linux/platform_data/
This patch moves the at24.h header from include/linux/i2c to
include/linux/platform_data and updates existing support accordingly.
It also fixes the following checkpatch warning:
WARNING: please, no space before tabs
#436: FILE: include/linux/platform_data/at24.h:31:
+ * ^Iu8 *mac_addr = ethernet_pdata->mac_addr;$
