Add support for the LiteX SD-Card device, LiteSDCard.

LiteSDCard is a simple SD-Card interface available as part of the LiteX
environment, used with various RISC-V and other FPGA based SoCs.

New in v2:
  - reword info message in litex_set_clk()
  - streamline code in litex_map_status()
  - fix typos in Kconfig (thanks Randy Dunlap [ref])
  - improvements suggested by Stafford Horne [ref]
    - allow COMPILE_TEST in Kconfig
    - use read_poll_timeout() when waiting for cmd/data/DMA
      xfer completion
  - include interrupt.h (thanks kernel test robot [ref])
