npcx: gpio: Change second tachometer source from TB2 to TA2.
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.
