The newly added cros_ec_lpc driver is meant for x86 but can
also be built on other architectures. However, the original
version causes a compile error when built on ARM because
of a missing #include:

drivers/platform/chrome/cros_ec_lpc.c: In function 'ec_response_timed_out':
drivers/platform/chrome/cros_ec_lpc.c:40:3: error: implicit declaration of function 'inb' [-Werror=implicit-function-declaration]
   if (!(inb(EC_LPC_ADDR_HOST_CMD) & EC_LPC_STATUS_BUSY_MASK))
   ^

This includes linux/io.h to make it compile reliably.
