This patchset adds support to basic version of Qualcomm NGD SLIMBus
controller driver found SoCs from B family.

This controller is light-weight SLIMBus controller driver responsible for
communicating with slave HW directly over the bus using messaging
interface, and communicating with master component residing on ADSP
for bandwidth and data-channel management.

Some parts fot the work is derived from Qualcomm downstream kernels
and intial work from
Karthikeyan Ramasubramanian <kramasub at codeaurora.org> and
Sagar Dharia <sdharia at codeaurora.org>

Tested this patchset on DB820c with WCD9335 codec and on msm8974 with
wcd9320 codec.

I have pushed my working branch to [1] incase someone want to try.

Changes sinc v1 (https://lkml.org/lkml/2018/5/25/296):
