[RFC PATCH] clk: keystone: Enable TISCI clocks if K3_ARCH

Quoting Nishanth Menon (2018-06-04 23:20:46)

K3_ARCH uses TISCI for clocks as well. Enable the same
for the driver support.

Hi,

This patch depends on https://marc.info/?l=linux-arm-kernel&m=152817866312732&w=2
and is an RFC based off next-20180604 and will post formally once
v4.18-rc1 is available.

Did you plan on sending it again soon? Otherwise I can just merge this
patch now.
