ANDROID: update .stg for change to struct clk_core

In commit a29ec046 ("clk: Get runtime PM before walking tree during
disable_unused"), the internal struct clk_core structure gets a new
field.  That disturbs the abi checker, as many apis use a pointer to
struct clk_core.  But because all callers treat this as an opaque
structure, and it is internal to the kernel core only, it is safe to
update the definition of it as there is no real "abi break" here at all.
