-> Fixes compile errors when including cros_ec_commands.h.

  platform/chrome: cros_ec_proto: add Kunit tests for

-> Adds Kunit tests for cros_ec_query_all().  They are baseline tests
   for the following refactor patches.  They are designed to pass current
   code.

  platform/chrome: cros_ec_proto: assign buffer size from protocol info
-> Refactors.

  platform/chrome: cros_ec_proto: remove redundant NULL check
-> Clean up.

  platform/chrome: cros_ec_proto: use cros_ec_map_error()
-> Changes the internal return code.

  platform/chrome: cros_ec_proto: separate cros_ec_get_proto_info()
-> Move refactor.

  platform/chrome: cros_ec_proto: add Kunit tests for getting proto info
  platform/chrome: cros_ec_proto: handle empty payload in getting proto
    info
-> Test and handle if send_command() returns 0 in cros_ec_get_proto_info().

  platform/chrome: cros_ec_proto: separate
    cros_ec_get_proto_info_legacy()
-> Move refactor.

  platform/chrome: cros_ec_proto: add Kunit test for getting legacy info
  platform/chrome: cros_ec_proto: handle empty payload in getting info
    legacy
-> Test and handle if send_command() returns 0 in
   cros_ec_get_proto_info_legacy().

  platform/chrome: cros_ec: don't allocate `din` and `dout` in
    cros_ec_register()
-> Clean up.

  platform/chrome: don't use devm variants for `din` and `dout`
-> Replace devm variants to non-devm.

  platform/chrome: cros_ec_proto: don't show MKBP version if unsupported
-> Minor fix up.

  platform/chrome: cros_ec_proto: return 0 on getting cmd mask success
-> Conform to kernel convention: return 0 on success;
   otherwise, negative integers.

  platform/chrome: cros_ec_proto: add Kunit test for getting cmd mask
    error
  platform/chrome: cros_ec_proto: check `msg->result` in getting cmd
    mask
-> Test and handle if `msg->result` isn't EC_RES_SUCCESS in
   cros_ec_get_host_command_version_mask().

  platform/chrome: cros_ec_proto: add Kunit tests for getting cmd mask
  platform/chrome: cros_ec_proto: handle empty payload in getting cmd
    mask
-> Test and handle if send_command() returns 0 in
   cros_ec_get_host_command_version_mask().

  platform/chrome: cros_ec_proto: return 0 on getting wake mask success
-> Conform to kernel convention: return 0 on success;
   otherwise, negative integers.

  platform/chrome: cros_ec_proto: add Kunit test for getting wake mask
  platform/chrome: cros_ec_proto: handle empty payload in getting wake
    mask
-> Test and handle if send_command() returns 0 in
   cros_ec_get_host_event_wake_mask().
