serial_rs485 contains padding at the end to make extending it easier.
Create kserial_rs485 counterpart w/o padding for kernel use leaving
serial_rs485 only to be used for uapi.

v2:
- Address style comments (from Andy)
- Convert most of the serial_rs485 & kserial_rs485 inline comments to
  kernel doc

Ilpo Järvinen (4):
  serial: Rename vars in uart_get_rs485_config()
  serial: add helpers to copy serial_rs485 from/to userspace
  serial: Convert serial_rs485 to kernel doc
  serial: Add kserial_rs485 to avoid wasted space due to .padding
