[PATCH v8 05/11] clk: meson: pll: export meson_clk_pll_wait_lock symbol

[Dmitry Rokosov <ddrokosov@sberdevices.ru>]

Modern meson PLL IPs are a little bit different from early known PLLs.
The main difference is located in the init/enable/disable sequences; the
rate logic is the same. So drivers for the new PLLs can be inherited
from the clk-pll driver and redefine init/enable/disable routines only.
For that purpose we need to have meson_clk_pll_wait_lock() in the export
symbols list, because each lock operation should be ended with wait
cycles.
