staging: ks7010: clean up SDIO source comments
SDIO code currently has a number of unneeded comments. Following kernel coding style we do not need extraneous comments, especially on code where it is clear what is being done. Spelling typos can be fixed. Remove unnecessary comments, fix typos in comments. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
