i2c: designware-baytrail: fix sparse warnings
There is no need to export functions that are used as the callbacks in the struct dw_i2c_dev. Otherwise we get the following warnings: drivers/i2c/busses/i2c-designware-baytrail.c:63:5: warning: symbol 'baytrail_i2c_acquire' was not declared. Should it be static? drivers/i2c/busses/i2c-designware-baytrail.c:114:6: warning: symbol 'baytrail_i2c_release' was not declared. Should it be static? While here, do few indentation fixes, remove i2c_dw_eval_lock_support() from functions exported to the modules and redundant assignment of local sem variable.
