Browse Source 
* Move filesystem mounting code into a separate file to simplify the
  main source file.
* Clean up SDMMC and SDSPI related code. Move pin configuration into
  Kconfig.
* Use same base_path ('/data') for either SPIFFS or SD. Remove the
  check in file_server.c about the base path.
* Update README according to the changes above.
