Subject: [PATCH v3 7/9] coresight: Consolidate clock enabling

CoreSight drivers enable pclk and atclk conditionally.  For example,
pclk is only enabled in the static probe, while atclk is an optional
clock that it is enabled for both dynamic and static probes, if it is
present.  In the current CoreSight drivers, these two clocks are
initialized separately.  This causes complex and duplicate codes.

This patch consolidates clock enabling into a central place.  It renames
coresight_get_enable_apb_pclk() to coresight_get_enable_clocks() and
encapsulates clock initialization logic:

 - If a clock is initialized successfully, its clock pointer is assigned
   to the double pointer passed as an argument.
 - If pclk is skipped for an AMBA device, or if atclk is not found, the
   corresponding double pointer is set to NULL.  The function returns
   Success (0) to guide callers can proceed with no error.
 - Otherwise, an error number is returned for failures.

The function became complex, move it from the header to the CoreSight
core layer and the symbol is exported.  Added comments for recording
details.

CoreSight drivers are refined so that clocks are initialized in one go.
As a result, driver data no longer needs to be allocated separately in
the static and dynamic probes.  Moved the allocation into a low-level
function to avoid code duplication.
