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 v10:
    - added casting to avoid sparse warnings in the SoC Controller's driver

Changes in v9:
    - fixed the `reg` node notation in the DT example
    - added exporting of the `litex_set_reg`/`litex_get_reg` symbols

Changes in v8:
    - fixed help messages in LiteUART's KConfig
    - removed dependency between LiteUART and LiteX SoC drivers
    - removed `litex_check_accessors()` helper function
    - added crashing (BUG) on the failed LiteX CSR access test

Changes in v7:
    - added missing include directive in UART's driver

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

Hello, as discussed offline I am planning to merge these via the OpenRISC tree
during 5.10.  If anyone has an issues let me know.

The patches all have their reviews and look fine to me other than a few nit's on
the soc controller patch.
