[PATCH V3 Resend 00/12] clk: Add non CONFIG_HAVE_CLK routines

[viresh.kumar@st.com (Viresh Kumar)]

Hi,

I am resending this patchset as Andrew didn't get few patches of this set. Also
i have updated patches with Acked-by or Reviewed by of people who replied with
these strings.

Last time there were few discussion over this patchset which can be found at

http://lkml.org/lkml/2012/4/24/154

Many drivers are shared between architectures that may or may not have HAVE_CLK
selected for them. To remove compilation errors for them we enclose clk_*()
calls in these drivers within #ifdef CONFIG_HAVE_CLK, #endif.

This patchset removes the need of these CONFIG_HAVE_CLK statements, by
introducing dummy routines when HAVE_CLK is not selected by platforms. So,
definition of these routines will always be available. These calls will return
error for platforms that don't select HAVE_CLK.

V2->V3:
- Dummy routines now return NULL or 0.
- All user drivers must fail if clk_get returned error other than NULL.
- All user drivers don't need to validate their clk pointer before every call to
  clk_*() routines.
- Patches dropped earlier are again taken back, as they were following similar
  approach to what is implemented now.
