ACPICA: Tables: Tune table mutex to be a leaf lock
ACPICA commit f564d57c6501b97a2871f0b4c048e79910f71783
This patch tunes MTX_TABLES into a leaf lock by always ensuring it is
released before holding other locks.
This patch also collects all table loading related functions into
acpi_tb_load_table() (invoked by load_table opcode) and
acpi_tb_install_and_load_table() (invoked by Load opcode and acpi_load_table()) so
that we can have lock tuning code collected at the boundary of these 2
functions. Lv Zheng.
