ata: libahci_platform: Add function returning a clock-handle by id
Since all the clocks are retrieved by the method
ahci_platform_get_resources() there is no need for the LLD (glue) drivers
to be looking for some particular of them in the kernel clocks table
again. Instead we suggest to add a simple method returning a
device-specific clock with passed connection ID if it is managed to be
found. Otherwise the function will return NULL. Thus the glue-drivers
won't need to either manually touching the hpriv->clks array or calling
clk_get()-friends. The AHCI platform drivers will be able to use the new
function right after the ahci_platform_get_resources() method invocation
and up to the device removal.
Note the method is left unused here, but will be utilized in the framework
of the DWC AHCI SATA driver being added in the next commit.
