This patchset introduces support for LiteX SoC Controller
and LiteUART - serial device from LiteX SoC builder
(https://github.com/enjoy-digital/litex).

In the following patchset I will add
a new mor1kx-based (OpenRISC) platform that
uses this device.

Later I plan to extend this platform by
adding support for more devices from LiteX suite.

Changes in v6:
- changed accessors in SoC Controller's driver
- reworked UART driver

Changes in v5:
- added Reviewed-by tag
- removed custom accessors from SoC Controller's driver
- fixed error checking in SoC Controller's driver

Changes in v4:
- fixed copyright headers
- fixed SoC Controller's yaml
- simplified SoC Controller's driver

Changes in v3:
- added Acked-by and Reviewed-by tags
- introduced LiteX SoC Controller driver
- removed endianness detection (handled now by LiteX SoC Controller driver)
- modified litex.h header
- DTS aliases for LiteUART made optional
- renamed SERIAL_LITEUART_NR_PORTS to SERIAL_LITEUART_MAX_PORTS
- changed PORT_LITEUART from 122 to 123

Changes in v2:
- binding description rewritten to a yaml schema file
- added litex.h header with common register access functions
