Some versions of this controller do not advertise their 3.0v and
8bit bus-width support capabilities. It is required to explicitly
set these capabilities for the specific controller versions.

PLL source index and register configuration value.

This patchset introduces the parent_map index tables, which solve the
issue discussed here [1].
While doing this, fix also some of the code around (patches 1 and 2)

According to the common clock framework API, the clk_get_parent() function
should return u8. Currently we are returning negative values on error. Fix
this and use the default parent in case of an error.

Boyd, reworked driver to use
index tables for clock parents.
* Split into two patches - DT binding and driver.
Changes since v1:
* Addressed comments from Stephen Boyd and Archit Taneja
* Fixed some incorrect offsets, parents etc.
* Driver is tested on MSM8916-MTP device.
