ACPICA: Events: Split acpi_ev_associate_reg_method() from region initialization code

Browse Source 
ACPICA commit 87c85610250ff7141a84507f68dbc1e00f2936db

This patch introduces a new region initialization function
acpi_ev_associate_reg_method(), which is invoked to associate the _REG method
to its related region object.

Region object's default value assignments are also sorted by cleaning up
the code using this new function. Lv Zheng.
