[PATCH 10/13] platform/chrome: cros_ec_proto: arrange get_host_command_version_mask()

[Tzung-Bi Shih]

- cros_ec_get_host_command_version_mask() is a private (static) function.
  Rename it to get_host_command_version_mask().

- Join multiple lines into one if it can fit in 100 columns.

- Don't show MKBP support version if it doesn't support.
