Manually generate .inc for all EC host commands:
sed ... include/linux/mfd/cros_ec_commands.h | awk ...
>drivers/platform/chrome/cros_ec_trace.inc

In cros_ec_trace.c:
#include "cros_ec_trace.inc"

cros_ec_trace.inc:
#ifndef EC_CMDS
#define EC_CMDS \
    ...
#endif

Override the whole file instead of replacing part of file to prevent
cut-and-paste error.
