In npcx's fan driver, ec selected mode 5 and capturer A as tachometer's input. Choosing TB2 as the second tachometer source is not correct since we didn't initialize the registers for TB2. This patch modified the second tachometer's input from TB2 to TA2 and passed the verification by following changes. 1. Add the second fan settings in pwm_channels, fans, and mft_channels arraies. 2. Modified ALTERNATE marco for pwm-type fans. 3. Set CONFIG_FAN from 1 to 2. 4. Set NPCX_TACH_SEL2 to 1 to test tachometer input 2. (ie.GPIO73/A6) BRANCH=none BUG=none TEST=test dual fans with fanset command on npcx_evb and use faninfo for verifying. Measure the actual rpm by scope.
