Series clk: meson: ee: use the new parent description method | expand

Commit Message

Alexandre Mergnat July 22, 2019, 9:54 a.m. UTC
This clock controller use the string comparison method to describe parent
relation between the clocks, which is not optimized.

Migrate to the new way by using .parent_hws where possible (ie. when
all clocks are local to the controller) and use .parent_data otherwise.
