staging: sm750fb: remove unused functions

Browse Source 
The functions sm750_enable_i2c() and sm750_hw_cursor_set_data2() are
defined and declared but never used. Following the driver's TODO list
to remove unused code, this patch deletes these dead functions.

Verified by compilation and cppcheck.
