i2c: npcm: fix consecutive dm_i2c_read/write error

When doing a dm_i2c_read followed by a dm_i2c_write, the subsequent
transaction may get npcm_i2c_check_sda error because the module is
still busy in STOP condition in previous dm_i2c_read.
Always check and wait for module to be out of busy before starting
an i2c transaction.
