staging: kpc2000: kpc_i2c: fixup block comment style in i2c_driver.c
Throughout i2c_driver.c, there are numerous deviations from the two standards of: - placing a '*' at the beginning of every line containing a block comment. - placing the closing comment marker '*/' on a new line. Instead, use a block comment style that is more consistent with the prescribed guidelines.
