KCS bridged

[Wang, Haiyue]

Hi Patrick,

Yes, the code is done and tested on AST2500 (by Intel BMC team)& NPCM750 
(by Avi from Nuvoton).

1. The ASPEED and the main KCS BMC stack has been in next tree:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/char/ipmi/kcs_bmc.c?h=next-20180327
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/char/ipmi/kcs_bmc_aspeed.c?h=next-20180327

2. The Nuvoton driver is on the fly:
https://lkml.org/lkml/2018/3/22/284 
<https://urldefense.proofpoint.com/v2/url?u=https-3A__lkml.org_lkml_2018_3_22_284&d=DwMGaQ&c=ue8mO8zgC4VZ4q_aNVKt8G9MC01UFDmisvMR1k-EoDM&r=kNeU5gwNy2cOhaTMIUoFhUPAXV51uTneHprahPM6I78&m=ID5-OH3zog6mXc13UaU1fkd107kOhusv44gfLsAYlzQ&s=3RwHjL1giz6-_bT-WPsD7nejvbVqOhCPjS2XB4Tchgs&e=>

After upstream finished, maybe it is the right time to push the 
kcsbridged into OpenBMC github,
and of course, the kcsbridged needs to be enhanced for real use in OpenBMC.

Haiyue
