Subject: [PATCH] i2c : i2c-algo-pcf : fixed errors and warnings in header file

Fixed code indent should use tabs error, missing '*' from
multiple line block comment warning, space prohibited after
paranthesis error and no space before tabs warning.
My motivation was to fix all errors and warnings in
drivers/i2c/algos/i2c-algo-pcf.h file.

Testing:
    * built kernel with my changes and I2C_ALGOPCF=m enabled
    and it built successfully.
    * installed kernel and external modules generated by build
    * rebooted and loaded using modprobe i2c-algo-pcf kernel module
    with param i2c_debug=3 and no message was found related to
    module in dmesg. But also no error was generated.
