Bill Richardson af77729737 Add build-time checks on board-specific array sizes. ...

We've been declaring a bunch of statically-sized arrays:

  extern struct foo_t foo[FOO_COUNT];

And then initializing them like so:

  struct foo_t foo[FOO_COUNT] = {
    /* blah */
  };

That only catches cases where we initialize with too many entries. It
doesn't catch cases where we haven't initialized enough. This change tests
for both cases like so:

  extern struct foo_t foo[];

  struct foo_t foo[] = {
    /* blah */
  };
  BUILD_ASSERT(ARRAY_SIZE(foo) == FOO_COUNT);

The affected arrays are:

  adc_channels[ADC_CH_COUNT]
  gpio_list[GPIO_COUNT]
  temp_sensors[TEMP_SENSOR_COUNT]
  x86_signal_list[X86_SIGNAL_COUNT]
  i2c_ports[I2C_PORTS_USED]

BUG=chrome-os-partner:18343
BRANCH=falco,peppy
TEST=build all platforms

All platforms should still build, all tests should still pass.
