[v2] clk: iproc: Make clocks visible options

Commit Message

Jon Mason Oct. 29, 2015, 8:44 p.m. UTC

Make the clocks visible options that can be selected by anyone.  This
avoids the problems of:
 1) Select is a reverse dependency and is hard for people to understand
    and can sometimes be a pain to track down
 2) Build coverage goes down because configs are hidden
 3) Code bloat

Patch suggested by Stephen Boyd

Applied to clk-next with some minor fixup in the Makefile. I know
this is almost a year old, but it still mostly applied.
